Abstract: An object of the present invention is to provide a coating composition that imparts excellent substrate adhesion and excellent processability to a cured coating film obtained by curing the coating composition. There is provided a coating composition comprising a base resin (A) and a polyester resin (B), wherein the polyester resin (B) contains a structural unit (b-1) derived from a polybasic acid and a structural unit (b-2) derived from a polyhydric alcohol, the structural unit (b-1) derived from a polyhydric alcohol contains 20 mol % or more and 100 mol % or less of a structural unit derived from hydrogenated bisphenol A, and the polyester resin (B) has a number average molecular weight of 500 to 4,500 and an acid value of 5 to 300.

Abstract: The objection of the present invention is to provide a photocurable resin composition having deep curability. The photocurable resin composition comprises an allyl polymer (a) produced by polymerization of an allyl compound represented by the following formula (1), a photocurable compound (b), and a photopolymerization initiator (c). In the formula, n represents an integer of 2 to 4; Z is selected from a binding site, an n-valent aliphatic chain hydrocarbon group optionally having a hydroxyl group, an n-valent alicyclic hydrocarbon group optionally having an alkyl group, and an n-valent aromatic hydrocarbon group optionally having an alkyl group; n is 2 and two —COOCH2CH═CH2 moieties are directly bonded to each other when Z is a binding site.
