Abstract

An object of the present invention is to provide a photocurable resin composition having excellent thick-film curability and further excellent storage stability, and a cured product of the photocurable resin composition has a high concealing effect.
The present invention is a photocurable resin composition containing components (A) to (E):
a component (A): a leuco dye; a component (B): a photoacid generator; a component (C): a radical polymerizable compound (except for a (meth)acrylate having a tertiary amine skeleton); a component (D): a photoradical polymerization initiator; and a component (E): a tertiary amine compound.

First claim

1 . A photocurable resin composition comprising components (A) to (E):
a component (A): a leuco dye; a component (B): a photoacid generator; a component (C): a radical polymerizable compound (except for a (meth)acrylate having a tertiary amine skeleton); a component (D): a photoradical polymerization initiator; and a component (E): a tertiary amine compound.

2 . The photocurable resin composition according to claim 1 , wherein
the component (E) is at least one member selected from the group consisting of N-phenyl diethanolamine, N-methyl diethanolamine, p-methylphenyl diethanolamine, N-ethyl diethanolamine, N-propyl diethanolamine, N-butyl diethanolamine, triethanolamine, tributanolamine, triisopropanolamine, N-methyl-diethanolamine, N-methyl-dimethanolamine, trimethylamine, triethylamine, tributylamine, N,N-dimethyl-p-toluidine, N,N-dimethyl-aniline, N,N-(dimethylamino)ethyl-methacrylate, N,N-dimethylamino acetophenone, N,N-dimethylamino benzophenone, N,N-diethylamino benzophenone, N-methylpiperidine, N-ethylpiperidine, N,N-dimethylbenzylamine, N,N-dimethylcyclohexylamine, acryloyl morpholine, morpholinoethyl (meth)acrylate, N,N-dimethylaminoethyl (meth)acrylate, N,N-diethylaminoethyl(meth)acrylate, N,N-dimethylaminoethyl (meth)acrylate, and N,N-dimethylaminopropyl (meth)acrylate.

3 . The photocurable resin composition according to claim 1 , comprising 0.01 to 200 parts by mass of the component (E) based on 100 parts by mass of the component (C).

4 . The photocurable resin composition according to claim 1 , comprising 0.01 to 100 parts by mass of the component (E) and 0.01 to 10 parts by mass of the component (B) based on 100 parts by mass of the component (C).

5 . The photocurable resin composition according to claim 1 , wherein
the component (C) comprises an oligomer and a monomer.

6 . The photocurable resin composition according to claim 1 , wherein
the component (D) comprises at least one of an acetophenone-based photoradical polymerization initiator and an acylphosphine oxide-based photoradical polymerization initiator.

7 . The photocurable resin composition according to claim 1 , wherein
the component (B) is an onium salt-based photoacid generator.

8 . The photocurable resin composition according to claim 1 , wherein
the component (B) is an aryl sulfonium salt.

9 . The photocurable resin composition according to claim 1 , wherein
a cured product is a black color.
