Abstract: A matte laminate film comprising a transparent resin film substrate and a matte layer formed on at least one surface of the transparent resin film substrate, in which the transparent resin film substrate is a laminate film comprising a layer (A) formed of a polycarbonate resin and a layer (B) formed of a methacrylic resin which is laminated on at least one surface of the layer (A). The matte laminate film is preferably used as a decorative film having good resistance to whitening and high mechanical properties and surface hardness.

Abstract: The present invention provides a matte resin film having a matte surface which allows a printed pattern to be clearly seen through a matte surface when the pattern is on a surface of the matte resin film opposite to the matte surface. The matte resin film has a resin film substrate and a matte layer formed on at least one surface of the resin film substrate, wherein the matte layer has a top surface that has a 60-degree specular gloss Gs being 5% to 60%, and wherein the matte resin film has a haze H that satisfies the inequality: H<70(%)?Gs. Preferably, the matte layer contains a transparent resin and transparent fine particles dispersed therein.

Abstract: A multilayer film for use in a simultaneous injection molding-lamination method comprising a layer (A) formed of a polycarbonate resin and a layer (B) formed of a composition of 85 to 100 parts by weight of a methacrylic resin and 0 to 15 parts by weight of acrylic rubber particles, which is laminated on at least one surface of the layer (A). The multilayer film is preferably used as a decorative film having high resistance to whitening and high surface hardness.

Abstract: A matte resin film comprising a resin film substrate and a matte layer formed on at least one surface of the substrate, wherein a 60 degree specular gloss Gs on the surface of the matte layer is 5% to 100%, a haze H satisfies the equation: H(%)<1400/Gs(%), and a 85 degree specular gloss Gs? on the surface of the matte layer is smaller than Gs, which exhibits an excellent matte effect even when a pattern is viewed at any viewing angle.

Abstract: Provided are a method for producing a crystalline methacrylic resin, the method comprising a step of bringing a mixture of an isotactic methyl methacrylate-type polymer and a syndiotactic methyl methacrylate-type polymer into contact with high pressure gas and a method for producing a plastic foam of the crystalline methacrylic resin, the method comprising a step of foaming the mixture. According to the method of the present invention, a crystalline methacrylic resin which is not limited in a form applicable to molded articles thereof and has high crystallinity and excellent solvent resistance can be obtained in a simple method and a plastic foam of the crystalline methacrylic resin can be obtained, the plastic foam embracing fine cells having an average cell diameter of about 10 &mgr;m or less and a cell number density of 109 to 1015 cells/cm3. Such a plastic foam is superior in the solvent resistance and in the mechanical properties such as impact resistance and bending strength.
