Title:
RESIN COMPOSITION FOR CARDS, AND SHEETS AND CARDS
Document Type and Number:
WIPO Patent Application WO/1999/009102
Kind Code:
A1
Abstract:
Plastics are improved in secondary processabilities so as, e.g., not to suffer curling by embossing, not to suffer card warpage upon exposure to high temperatures, to give flat sections upon card formation by punching, and to have satisfactory releasability from the press plates. According to the properties required, various means are taken to modify substantially noncrystalline polyester resins. For example, a mixture of polyethylene glycol with a sodium alkylbenzenesulfonate in a weight ratio of from 1/9 to 9/1 is added to the resin in an amount of 0.2 to 1.5 % by weight. Alternatively, powdery silicic acid and/or powdery magnesium silicate each having an average particle diameter of 5 $g(m)m or smaller is incorporated in an amount of 0.5 to 5.0 % by weight, or a particulate and/or flaky inorganic filler having an average particle diameter of 3 to 10 $g(m)m is incorporated.
