Abstract:
A photohardenable resin composition comprising:(i) at least one urethanated acrylic compound represented by formula (I): (A)aâ€”Câ€”(R)4âˆ’aâ€ƒâ€ƒ(I) â€ƒwherein R represents a hydrogen atom or an alkyl group; a represents 3 or 4; and A represents a group represented by formula (II): â€ƒwherein D represents â€”CH2CH2Oâ€”, â€”CH2CH(CH3)Oâ€”, â€”CH2CH2COOâ€” or â€”(CH2)6COOâ€”; E represents â€”CH2CH2Oâ€”, â€”CH2CH(CH3)Oâ€”, â€”COCH2CH2Oâ€” or â€”CO(CH2)6Oâ€”; G represents a triol residual group; J represents a divalent or trivalent and substituted or unsubstituted hydrocarbon group; L represents â€”(CH2CH2O)hâ€”, wherein h represents an integer of 1 to 4, â€”(CH2CH(CH3)O)jâ€”, wherein j represents an integer of 1 to 4, or â€”(CH2CH2O)kâ€”(CH2CH(CH3)O)mâ€”, wherein k and m each represent an integer of 1 to 3 provided that the sum of k and m is 2, 3 or 4; b and c each represent 0 or 1, provided that the sum of b, c, and d is 1, 2 or 3; d=e=f=1; and g represents 1 or 2; (ii) a radical polymerizable compound other than said urethanated acrylic compound of formula (I); and (iii) a photosensitive polymerization initiator, wherein the weight ratio of said urethanated acrylic compound (i) to said radical polymerizable compound (ii) is in the range of from 80:20 to 10:90.
