Problems solved by technology

However, since the sheet-like temporary fixing agent is difficult to manage the thickness of the resin layer and requires an additional crimping process when laminating, it has the disadvantage of significantly reducing workability

Abstract

[Problem] The present invention provides an acrylic resin composition which has low viscosity, which can be cured even by an LED irradiation device having low illuminance, and which provides a cured product that has adequate peel strength without addition of an additive for forced peeling, said cured product also having both toughness and bendability. [Solution] An acrylic resin composition which contains components (A)-(D) as essential ingredients, with component (B) being contained in an amount of 1,000-2,000 parts by mass, component (C) being contained in an amount of 30-250 parts by mass and component (D) being contained in an amount of 10-100 parts by mass, respectively per 100 parts by mass of component (A). Component (A): an acrylic oligomer Component (B): an acrylic monomer which contains components (b-1)-(b-3), respectively in an amount of at least 20% by mass of component (B) Component (b-1): an ether group-containing acrylic monomer and / or an ester group-containing acrylic monomer Component (b-2): a cyclic hydrocarbon group-containing acrylic monomer Component (b-3): an aromatic group-containing acrylic monomer Component (C): a thiol compound Component (D): a photoinitiator

Description

technical field [0001] The present invention relates to an acrylic resin composition which has good handleability due to its low viscosity, and which is easy to peel from an adherend due to its toughness and toughness of the cured product due to its moderate peel strength. Background technique [0002] As the thiolene reaction, the reaction of a vinyl group such as an acryl group, a methacryl group, or a vinyl ether group with a thiol group has been used industrially. In particular, when a photoinitiator is added to a composition containing an acrylic group, it can be cured by irradiation with energy rays. In recent years, as in Patent Document 1, plastic lenses have been molded by photocuring using an acrylic compound and a polyfunctional thiol compound. It is considered that the use of a polyfunctional thiol compound increases the crosslinking density of the cured product, and since it is molded into a transparent and very hard cured product, it is considered suitable for...
