Abstract

Disclosed are an epoxy acrylate resin of the general formula (1) ##STR1## and an acid-modified epoxy acrylate resin obtained by reacting the epoxy acrylate resin with a carboxylic acid or an anhydride thereof, as well as curable resin compositions containing such a resin and the cured products thereof.

Claims

1. An epoxy acrylate resin of the general formula (1):

##STR7## wherein each R¹ is independently a hydrogen atom, a straight-chain, branched or cyclic alkyl group, an alkoxy group, a nitro group or a halogen atom, each R² is independently a hydrogen atom or a methyl group, m is an integer of 1 to 3, and n is an integer of 0 to 10.

4. A curable resin composition containing an epoxy acrylate resin as claimed in claim 1.

7. A solder resist composition containing an epoxy acrylate resin as claimed in claim 1.

10. The cured product obtained by curing a composition as claimed in claim 4.

13. The cured product obtained by curing a composition as claimed in claim 7.

16. The epoxy acrylate resin of claim 1 wherein R¹ is a straight chain, branched or cyclic alkyl group substituted with a group selected from the group consisting of alkoxy groups, alkoxy-alkoxy groups, aryloxy groups, aryloxy-alkoxy groups and halogen atoms.

17. The epoxy acrylate resin of claim 1 wherein R¹ is an alkoxy group substituted with a group selected from the group consisting of alkoxy groups, alkoxy-alkoxy groups, aryloxy groups, aryloxy-alkoxy groups and halogen atoms.

2. An epoxy acrylate resin derived from an epoxy resin of the general formula (2) ##STR8## wherein each R¹ is independently a hydrogen atom, a straight-chain, branched or cyclic alkyl group, an alkoxy group, a nitro group or a halogen atom, m is an integer of 1 to 3, and n is an integer of 0 to 10, and at least one compound selected from the group consisting of acrylic acid.

3. An acid-modified epoxy acrylate resin obtained by reacting an epoxy acrylate resin as claimed in claim 2 with a carboxylic acid or an anhydride thereof.

5. A curable resin composition containing an epoxy acrylate resin as claimed in claim 2.

6. A curable resin composition containing an epoxy acrylate resin as claimed in claim 3.

8. A solder resist composition containing an epoxy acrylate resin as claimed in claim 2.

9. A solder resist composition containing an epoxy acrylate resin as claimed in claim 3.

11. The cured product obtained by curing a composition as claimed in claim 5.

12. The cured product obtained by curing a composition as claimed in claim 6.

14. The cured product obtained by curing a composition as claimed in claim 8.

15. The cured product obtained by curing a composition as claimed in claim 9.

18. The epoxy acrylate resin of claim 2 wherein R¹ is a straight chain, branched or cyclic alkyl group substituted with a group selected from the group consisting of alkoxy groups, alkoxy-alkoxy groups, aryloxy groups, aryloxy-alkoxy groups and halogen atoms.

19. The epoxy acrylate resin of claim 2 wherein R¹ is an alkoxy group substituted with a group selected from the group consisting of alkoxy groups, alkoxy-alkoxy groups, aryloxy groups, aryloxy-alkoxy groups and halogen atoms.
