ABSTRACT:
The present invention is to provides an ultraviolet-curable resin composition which contains a composite resin (A) having a polysiloxane segment (a1) having a silanol group and/or a hydrolytic silyl group as well as a polymerizable double bond and a polymer segment (a2) other than the polysiloxane segment (a1), and a photo initiator (B). The ultraviolet-curable resin composition is able to form a cured coating film excellent in weatherability such as scratch resistance, acid resistance, alkali resistance and solvent resistance, without heating.
