摘要 |
A polybutylene terephthalate laminate film having excellent shape memory and high-temperature dimensional stability obtained by (1) subjecting a laminate film comprising a polybutylene terephthalate film and another film or film laminate to a shaping treatment at a temperature T1 equal to or lower than the glass transition temperature of said polybutylene terephthalate while maintaining a first shape; (2) deforming the shaped laminate film to a second shape at a temperature T2 higher than said glass transition temperature; and (3) cooling said laminate film to a temperature T3 equal to or lower than said glass transition temperature. <IMAGE> |
