Abstract
The present invention relates to a photocurable composition which exhibits excellent adhesiveness not only to thermoplastic resins such as PET and polyimide but also to adherends of metal oxides such as IZO and metals such as gold, more particularly to a photocurable composition which comprises a urethane oligomer (A) having two or more allyl ether and/or vinyl ether groups and a polythiol (B) having two or more thiol groups.
Claims5
A photocurable composition comprising:
- a urethane oligomer (A) having two or more allyl ether and/or vinyl ether groups;
- and a polythiol (B) having two or more thiol groups,
- wherein the urethane oligomer (A) is a urethane oligomer derived from a urethane prepolymer, the urethane prepolymer being synthesized from (i) polypropylene glycol and isophorone diisocyanate or from (ii) polyether polyol and isophorone diisocyanate,
- the urethane oligomer (A) is a urethane oligomer synthesized from the urethane prepolymer and allyl ether glycol and/or hydroxybutyl vinyl ether, and
- the polythiol (B) is a polythiol derived from mercaptocarboxylic acid.
