PROBLEM TO BE SOLVED: To provide ligneous woodgrained vinyl chloride base resin window frames excellent in impact resistance, water resistance and hot water resistance by melt molding vinyl chloride based resin compositions capable of inhibiting a bleeding phenomenon due to water and hot water in weatherability and obtaining woodgrain patterns in integrally molded articles which does not require a surface treatment step and laminating specifications and, additionally, improved in the exhibition of a ligneous feeling. SOLUTION: Ligneous woodgrained vinyl chloride based resin frames are obtained by subjecting a vinyl chloride based resin composition obtained by mixing 0.1-30 pts.wt. vinyl chloride based resin composition containing 0.001-10 wt.% pigment with 100 pts.wt. mixture B which has been obtained by adding 0.1-5 pts.wt. cashew shell oil-modified phenolic resin to 100 pts.wt. mixture A composed of 50-99 pts.wt. vinyl chloride based graft copolymer obtained by graft copolymerizing vinyl chloride onto a copolymer of an alkyl acrylate and/or an alkyl methacrylate with a polyfunctional monomer and 50-1 pts.wt. crosslinked vinyl chloride based resin to melt molding.
