- (C) a compound having at least one epoxy group and having no ethylenic unsaturated double bond, wherein said component is present in an amount of from about 1 to 40 parts by weight based on 100 parts by weight of the solid components of said liquid light-sensitive resin composition;
- (D) a photopolymerization initiator or a photopolymerization initiating system wherein said photopolymerization initiator or said photopolymerization initiating system is present in an amount of from about 0.1 to 20 parts by weight based on 100 parts by weight of the solid components of said liquid light-sensitive resin composition;
- (E) a thermohardening catalyst capable of inducing a thermal reaction of said at least one epoxy group wherein said thermohardening catalyst is present in an amount of from about 0.01 to 10 parts by weight based on 100 parts by weight of the solid components of said liquid light-sensitive resin composition; and
- (F) an organic solvent which is different from components (B) and (C) above and wherein said organic solvent is present in an amount of form about 10 to 50 parts by weight based on 100 parts by weight of said liquid light-sensitive resin composition.
- 2. A liquid light-sensitive resin composition as claimed in claim 1, wherein said modified polystyrene resin is:
- (A-1) a modified polystyrene resin obtained by reacting a polymer having a repeating unit of the following general formula (I): ##STR7## wherein R represents a hydrogen atom or a methyl group; and Ar represents an unsubstituted or substituted phenylene group;
- successively with a compound having an epoxy group and an ethylenic unsaturated double bond in a single molecule in an amount of from about 0.5 to 1.2 equivalent(s) per equivalent of the hydroxyl group in said polymer having a repeating unit of general formula (I) and a saturated or unsaturated polybasic acid anhydride in an amount of from bout 0.1 to 1.1 equivalent(s) per equivalent of the hydroxyl group in said polymer having a repeating unit of general formula (I).
- 3. A liquid light-sensitive resin composition as claimed in claim 1, wherein said modified polystyrene resin is:
- (A-2) a modified polystyrene resin obtained by reacting a polymer having a repeating unit of the following general formula (II); ##STR8## wherein R represents a hydrogen atom or a methyl group; and Ar represents an unsubstituted or substituted phenylene group;
- successively with a compound having a carboxyl group and an ethylenic unsaturated double bond in a single molecule in an amount of from about 0.5 to 1.2 equivalent(s) per equivalent of the hydroxyl group in said polymer having a repeating unit of general formula (II) and a saturated or unsaturated polybasic acid anhydride in an amount of from about 0.1 to 1.1 equivalent(s) per equivalent of the hydroxyl group in said polymer having a repeating unit of general formula (II).
- 4. A liquid light-sensitive resin composition as in claim 2, wherein said compound having an epoxy group and an ethylenic unsaturated double bond in a single molecule is a compound selected from the group consisting of glycidyl acrylate and glycidyl methacrylate and said saturated or unsaturated polybasic acid anhydride is a compound selected from the group consisting of succinic anhydride and tetrahydrophthalic anhydride.
- 5. A liquid light-sensitive resin composition as claimed in claim 3, wherein said compound having a carboxyl group and an ethylenic unsaturated double bond in a single molecule is a compound selected from the group consisting of acrylic acid, methacrylic acid and dimers, trimers and higher polymers of acrylic acid and said saturated or unsaturated polybasic acid anhydride is a compound selected from the group consisting of succinic anhydride and tetrahydrophthalic anhydride.
