Abstract
Abstract A molding having a grain resembling a natural material such as wood, stone and the like and a method for producing the same are disclosed. The molding is made of a mixture of a colored polyphenyleneoxide resin and a thermoplastic resin. The polyphenyleneoxide resin has a low fluidity to form patterns, while the thermoplastic resin has a high fluidity to form a body.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
59 words
A molding having a grain resembling a natural material comprising a mixture of 0.1-20% by weight of colored modified polyphenyleneoxide resin and 80-99.9% by weight of thermoplastic, said thermoplastic resin having a higher fluidity in the range of molding temperature than said polyphenyleneoxide resin and selected from group consisting of styrene resin, polyolefine resin, polyvinylchloride resin and polymethylmethacrylate resin.
Claim 2
Dependent Claim
59 words
A molding having a grain resembling a natural material comprising a mixture of 0.1-20% by weight of colored modified polyphenyleneoxide resin and 80-99.9% by weight of thermoplastic, said thermoplastic resin having a higher fluidity in the range of molding temperature than said polyphenyleneoxide resin and selected from group consisting of styrene resin, polyolefine resin, polyvinylchloride resin and polymethylmethacrylate resin.
Claim 3
Independent Claim
44 words
A method for making molding having a grain resembling a natural material which comprises admixing 0.1-20% by weight of colored modified polyphenyleneoxide resin with 80-99.9% by weight of thermoplastic resin and molding said mixed resin in a molder at a temperature of 170°-300° C.
Claim 4
Independent Claim
44 words
A method for making molding having a grain resembling a natural material which comprises admixing 0.1-20% by weight of colored modified polyphenyleneoxide resin with 80-99.9% by weight of thermoplastic resin and molding said mixed resin in a molder at a temperature of 170°-300° C.
Claim 5
Dependent Claim
27 words
