Abstract
The invention provides a printing ink less susceptible to decoration rolling in association with a decorated film or sheet used for integral injection molding. The ink of the present invention is used for printing of a decorated film or sheet integrated with a synthetic resin melt at a synthetic resin molding step to apply a decoration on a molded article simultaneously with molding, and comprises a binder comprising a polycarbonate resin, and a metal particle coated on the surface thereof with a coupling agent or a synthetic resin.
Claims5
An ink used for printing of a preprinted film or sheet used for decorating a molded article by integration with a synthetic resin melt at a synthetic resin molding step, comprising:
- a binder comprising a polycarbonate resin, and
- a metal particle coated on the surface thereof with a coupling agent or a synthetic resin.
A printed film or sheet used for decorating a molded article by integration with a synthetic resin melt at a synthetic resin molding step, which has been obtained by printing a synthetic resin film with an ink comprising a binder comprising a polycarbonate resin and a metal particle coated on the surface thereof with a coupling agent or a synthetic resin.
A synthetic resin injection molding method wherein a printed film or sheet is prepared by printing using an ink containing a metal particle coated on the surface thereof with a coupling agent or a synthetic resin, the printed film or sheet is then placed in a metal mold, and a synthetic resin melt is finally subjected to injection molding at a temperature of 200° C. or higher.
