摘要： Provided is a resin composition based on polyalkylene carbonate for use as an adhesive film composition for glass lamination, and more particularly, to a resin composition in which a plasticizer and isocyanate are added to polypropylene carbonate or polyethylene carbonate as polyalkylene carbonate to introduce a urethane group. As such, the resin composition of the present invention can improve an adhesive strength by addition of isocyanate, and secure flexibility by using the plasticizer. In particular, an adhesive sheet based on polyalkylene carbonate can decompose a polymer laminate layer through simple heat treatment to fully collect glass when defects of glass lamination are generated, thereby reducing the loss of glass due to process failure, be stable to moisture so that transport, storage, and use thereof are not limited, and perform lamination even at a lower process temperature.

摘要： Provided is a polypropylene carbonate (hereinafter, PPC) paint composition, and more particularly, a pre-coated metal (PCM) paint composition for coil coating, which is mainly applied to cases for home appliances requiring high hardness, such as cases of a refrigerator. The composition can be used to provide a PCM paint, which has very low smoke density at the time of burning and emits remarkably low amounts of combustion gas and poisonous gas due to combustion at the time of firing, as compared with the existing laminate steel plate and a high-gloss film. In addition, the composition exhibits excellent adhesion to metal materials and excellent durability so that it can be usefully used for a PCM print steel plate applied to home appliances.
