发明名称 Sheet for decoration simultaneous with injection molding and decorated resin molding
摘要 The present invention provides a laminate-type decorative sheet for use in simultaneous decoration and injection molding, including a base film and at least a decorative layer provided on the base film, the decorative sheet having an elongation at break as measured at 25° C. of 3 to 10%, and an elongation at break as measured at 120° C. of 200% or more.;The laminate-type decorative sheet exhibits good conformability to the molding surface of a mold during the course of preforming, and is less likely to produce wrinkling, blistering, breakage, etc. when laminated on and united with a resin molding through injection molding. In addition, the decorative sheet enables easy trimming.

主权项 1. A method for producing a decorated resin molded product, comprising: (a) injection molding a resin into a mold having a decorative sheet in the mold, to form a resin molding, such that the decorative sheet is laminated on and united with the resin molding; and (b) removing from the mold the resin molding laminated with an entirety of the decorative sheet, wherein the removing of the resin molding includes trimming of an excess portion of the decorative sheet provided along a periphery of the resin molding, wherein the decorative sheet is a laminate, and comprises a base film and at least a decorative layer provided on the base film, the decorative sheet having an elongation at break as measured at 25° C. of 3 to 10%, and an elongation at break as measured at 120° C. of 200% or more, and both the elongation at break as measured at 25° C. and 120° C. are measured in all directions including MD, being a flow direction during formation of the base film, and TD, being a direction perpendicular to MD, wherein the base film includes at least one rubber material selected from the group consisting of acrylic rubber, butadiene rubber and silicone rubber, and wherein the decorative sheet is simultaneously subjected to decoration and injection molding.
