This specification discloses durable In-MoId Decoration (IMD) laminates made by using semi- crystalline polymers as top films. The crystalline structure or content of the semi-crystalline polymer can be optimized with a post process treatment process, which leads to improved chemical resistance and scratch resistance. The post process treatment can be conducted after the making of the film, during the in-mold processing of the laminate or after the in-mold processing of the laminate. The treatment can be applied over the entire film surface or in discrete areas with the treatment depth ranging from the top surface up to the bottom surface of the film. The post process treatment can be accompanied by changes in the appearance of the top film which makes IMD products tunable in decoration luster appearance. Durable IMD laminates with 60 degree gloss value of greater than 90 and process of making such laminates are also disclosed.
