<p>An improved active energy ray-curing resin composition comprising (i) a graft copolymerized polymer with a trunk chain containing dicyclopentenyl derivative group which has a number average molecular weight of 5,000 or more and a weight average molecular weight of 50,000 or less: (ii) a linear polymer having a number average molecular weight of 5,000 or more and a weight average molecular weight of 350,000 or less and having a glass transition temperature of 60 DEG C or more: (iii) a monomer having an ethylenically unsaturated bond: and (iv) a photopolymerization initiator capable of generating free radicals with irradiation of an active energy ray. The resin composition can be desirably cured with an active energy ray such as ultraviolet ray or electron beam and it is capable of being laminated in a desired pattern on a cupper-coated laminate for use as a printed board or on a plate of metal, glass, ceramics or plastic.</p> |
