Claim 2
Dependent Claim
59 words
A halogen-containing resin composition comprising a mixture of (A) 100 parts by weight of a halogen-containing resin, (B) 0.01 to 5 parts by weight of a copper glycinate having the formual of Cu(NH 2 CH 2 CO 2 ) 2 .H 20 , and (C) 0.01 to 5 parts by weight of a metal salt of an organic acid.
Claim 3
Dependent Claim
21 words
