Title:
POLYLACTIC ACID-BASED CARD MATERIAL AND CARD
Document Type and Number:
WIPO Patent Application WO/2006/104013
Kind Code:
A1
Abstract:
Disclosed is a polylactic acid-based card material which is excellent in both mechanical strength and hydrolysis resistance even when a polylactic acid polymer is used as a main component. This polylactic acid-based card material maintains sufficient transparency even when an aliphatic polyester is added thereto. This polylactic acid-based card material is characterized by blending 0.3-6 parts by mass of an aliphatic polycarbodiimide compound (c) having a terminal isocyanate group per 100 parts by mass of a resin composition which is composed of 50-90% by mass of a polylactic acid polymer (a) and 50-10% by mass of an aliphatic polyester (b) other than polylactic acid polymers which has a glass transition temperature (Tg) of not more than 0&ring C.
