Problems solved by technology

[0005] The object of the present invention is to overcome the above-mentioned deficiencies of the prior art, and to provide a photopolymerizable photosensitive polymer material, aiming to solve the problems caused by the photopolymerizable photosensitive polymer material containing plasticizer in the prior art. The holographic image formed by the exposure of molecular materials at room temperature will undergo deformation or color change, is not environmentally friendly, and has poor quality and weak anti-counterfeiting when used as a packaging material.

preparation example Construction

[0031] As a preferred embodiment, the preparation method of the above-mentioned acrylate film-forming resin comprises the following steps:

[0032] (1) Based on the calculation of 100% of the total weight of the above-mentioned acrylate film-forming resin prepolymer, the following components are weighed by weight percentage:

[0033]

[0034] (2) Dissolving the weighed acrylate monomer and thermal initiator in the above solvent for reaction, then adding fluorine-containing acrylate monomer, and discharging to obtain acrylate film-forming resin prepolymer.

[0035] In the above step (1), the acrylate monomer should contain at least one acrylate hydroxy ester monomer, and the terminal hydroxyl group is used for polyurethane reaction with the isocyanate group of the subsequent polyisocyanate curing agent.

[0036] Since the transmittance of the acrylate random copolymer is better, which is beneficial to the subsequent exposure of the photopolymerizable photosensitive polymer m...

Embodiment 1

[0071] A photopolymerizable photosensitive polymer material, which contains the following components by weight percentage:

[0072]

[0073] And, prepare above-mentioned acrylate film-forming resin prepolymer by following two steps:

[0074](1) Based on the total weight of the above-mentioned acrylate film-forming resin prepolymer as 100%, weigh the following components by weight percentage:

[0075]

[0076] (2) The weighed methyl methacrylate, isooctyl methacrylate, hydroxypropyl acrylate and azobisisobutyronitrile are subjected to free radical reaction in a solvent, the reaction temperature is 70-90°C, and the reaction time is After 2-3 hours, add 2-(perfluorobutyl)methyl ethyl acrylate dropwise, continue to stir and mix, and continue to react at 70-90°C for 1 hour to form an acrylate film-forming resin. Afterwards, the viscosity-average molecular weight of the prepared film-forming resin is tested according to the existing gel chromatography and viscosity method unt...

Embodiment 2

[0088] A photopolymerizable photosensitive polymer material, which contains the following components by weight percentage:

[0089]

[0090] This embodiment 2 is basically the same as the steps of preparing acrylate film-forming resin, polyisocyanate curing agent and photopolymerizable photosensitive polymer material in the above embodiment 1, the only difference is that polyether binary resin is used when preparing polyisocyanate curing agent Alcohol replaces the dihydric alcohol of the saturated alkane main chain as a chain extender, the high refractive index monomer is ethoxylated bisphenol A dimethacrylate and 4-cumylphenoxyethyl acrylate, and the photoinitiator is chlorinated bisphenol A imidazole.

[0091] Based on 100% of the total weight of the polyisocyanate curing agent, the following components are weighed in percentage by weight:

[0092] Isophorone diisocyanate 23.77%;

[0093] Polyether diol SC-204 21%;

[0094] Butanone 55.23%.

Abstract

The invention discloses a photopolymerizaiton-typed photosensitive high-molecular material which includes, by weight, 5%-50% of an acrylate film-forming resin prepolymer, 5%-50% of a polyisocyanate curing agent, 5%-40% of an acrylic acid monomer, 0.05%-5% of a photoinitiator and 30%-70% of a solvent. The photopolymerizaiton-typed photosensitive high-molecular material is free of a plasticizer so that a hologram is not liable to deform or change in color and is enhanced in stability, wherein the hologram is formed from the photopolymerizaiton-typed photosensitive high-molecular material through normal-temperature exposure. In addition, with a double-component system composed of the acrylate film-forming resin prepolymer and the polyisocyanate curing agent, the photopolymerizaiton-typed photosensitive high-molecular material is enhanced in comprehensive performance and a step of covering a surface of the photopolymerizaiton-typed photosensitive high-molecular material by a protective film is further avoided when the photopolymerizaiton-typed photosensitive high-molecular material is used. A product produced by the photopolymerizaiton-typed photosensitive high-molecular material is reduced in thickness and is enhanced in anti-fake performance.

Description

technical field [0001] The invention relates to the field of holographic photosensitive recording materials, in particular to a photopolymerizable photosensitive polymer material, a preparation method and an application thereof. Background technique [0002] Holographic technology has developed rapidly in recent years and has been widely used in non-destructive testing, 3D display, 3D storage, optical components, anti-counterfeiting, packaging, printing and other fields. Among the holographic photosensitive recording materials, silver halide materials, dichromate gelatin materials and photosensitive polymer materials are widely used. The photosensitive polymer material has high sensitivity, high resolution, high diffraction efficiency and simple processing, and is an ideal holographic recording material. Photosensitive polymer holographic recording materials can be roughly divided into three categories: photopolymerization type, photocrosslinking type and photodecomposition...
