Problems solved by technology

[0007] However, in the production method of the uneven surface sheet, when the above-mentioned conventional production method of the uneven surface sheet is used, there is a problem that the sheet with the uneven surface is limited to the one with a high modulus of elasticity, and it is necessary to remove the volatile components by evaporation. The problem of time-consuming and the problem that the vapor of volatile components has adverse effects on human body or environment

Embodiment 1

[0383] The particle-combined photopolymerizable composition (A) is coated on the release-treated surface of the above-mentioned cover film so that the thickness after curing becomes 100 μm, and a particle-combined photopolymerizable composition layer is formed, which is combined with a monomer absorbing layer and The form in which the particles are in contact with the photopolymerizable composition layer is bonded to the substrate-attached monomer-absorbing sheet (A) in which the monomer-absorbing layer has been peeled off to form a laminate.

[0384] Next, ultraviolet rays (illuminance: 5 mW / cm 2 ), the particles are combined with the photopolymerizable composition layer to be photocured to form a particle-coordinated photopolymerization cured layer, thereby producing a sheet with uneven surface.

Embodiment 2

[0386] The particle-combined photopolymerizable composition (B) is coated on the release-treated surface of the above-mentioned cover film so that the thickness after curing becomes 50 μm, and a particle-combined photopolymerizable composition layer is formed, which is separated by a monomer-absorbing layer and The form in which the particles are in contact with the photopolymerizable composition layer is bonded to the substrate-attached monomer-absorbing sheet (A) in which the monomer-absorbing layer has been peeled off to form a laminate.

[0387] Next, 1 minute after forming the laminated body, the laminated body was irradiated with ultraviolet rays (illuminance: 5 mW / cm 2 ), the particles are combined with the photopolymerizable composition layer to be photocured to form a particle-coordinated photopolymerization cured layer, thereby producing a sheet with uneven surface.

Embodiment 3

[0389] The particle-combined photopolymerizable composition (A) is coated on the release-treated surface of the above-mentioned cover film so that the thickness after curing becomes 60 μm, and a particle-combined photopolymerizable composition layer is formed, and the monomer-absorbing layer and the The form in which the particles are in contact with the photopolymerizable composition layer is bonded to the substrate-attached monomer-absorbing sheet (B) in which the monomer-absorbing layer has been peeled off to form a laminate.

[0390] Next, 1 minute after forming the laminated body, the laminated body was irradiated with ultraviolet rays (illuminance: 5 mW / cm 2 ), the particles are combined with the photopolymerizable composition layer to be photocured to form a particle-coordinated photopolymerization cured layer, thereby producing a sheet with uneven surface.

Abstract

Disclosed is a polymer article having a multilayer structure including a polymer layer and a monomer-absorptive layer that is arranged on the polymer layer and is capable of absorbing at least one of monomer components constituting the polymer. The polymer layer is a polymer layer containing an unevenly distributed immiscible material that is immiscible with the polymer and is enriched at an interface, or in the vicinity thereof, opposite to the monomer-absorptive layer. The polymer article preferably further includes a cover film arranged on the polymer layer on a side opposite to the monomer-absorptive layer. The vicinity of the interface opposite to the monomer-absorptive layer is preferably a region ranging from the interface opposite to the monomer-absorptive layer in a thickness direction to 50% or less of the total thickness of the polymer layer.

Description

technical field [0001] The present invention relates to a polymer part having a polymer layer with inhomogeneous distribution of incompatible substances and a surface relief strip or sheet made of the polymer part. Background technique [0002] For example, when forming a layer having fine particles on the surface of a sheet or film to be a base material, the fine particles are dispersed in a solution obtained by dissolving a polymer component as a binder in an organic solvent, coated on the base material, and then By volatilizing the solvent by thermal drying, a microparticle layer (layer containing microparticles) can be obtained on the surface of the substrate. This method is difficult when the base material is dissolved by a solvent or the like, or the base material has low heat resistance, melts due to heat drying, and is easily deformed. In addition, when the surface is rich in adhesiveness like an adhesive layer, Coating on the surface of the material also becomes di...
