A molding die is devised to suppress the formation of a fragile layer, thereby ensuring stable production of a resin molded body having remarkably improved adhesion of a plating film. A plurality of stepped parts are formed so as to be spaced apart from each other on a second die surface which molds a back surface on the side opposite to a design surface to which metal plating is to be applied, along the main flowing direction of a molten resin and in a direction crossing the main flowing direction. Since the flow of the molten resin changes due to the stepped parts and the influence thereof extends even to the vicinity of the design surface, the formation of a fragile layer is suppressed.

Resin injection molding die and method for producing resin molded product

The present invention provides an electromagnetic wave-permeable brilliant coated resin product which has a brilliant coating film formed by applying a coating composition that includes a planar brightening material formed from aluminum, on a resin substrate. Within the brilliant coating film, the brightening material is oriented in a state such that a plane thereof is biased toward a direction that follows a surface of the brilliant coating film, and an average overlapping quantity (y), which is an average of a quantity of brightening material that crosses one orthogonal line that is orthogonal to the surface of the brilliant coating film, and an average inter-brightening material distance (x), which is an average of distances on the orthogonal line between adjacent brightening materials that cross said orthogonal line, satisfy the following two formulae:y&#x2267;0.5 &#x2003;&#x2003;(formula 1), and&#x2266;0.3969+0.594 &#x2003;&#x2003;(formula 2),

Electromagnetic wave-permeable brilliant coated resin product and manufacturing method therefor

A resin product (e.g., a millimeter-wave radar device cover) comprises a plate-like resin substrate, a base film formed on the resin substrate, and a metallic gloss film having a discontinuous structure formed on the base film, a top coat, a block coat, or the like being formed as a protective film on the metal film. The metal film contains a first film having a discontinuous structure obtainable by vacuum deposition of a first metal, a modified surface obtainable by modification of the surface of the first film by bringing the surface into contact with air, and a second film having a discontinuous structure obtainable by vacuum deposition of a second metal on the modified surface.

Resin product

The present invention provides a metallic coating having a sheen and discontinuous structure and a resin product having the metallic coating by using a physical vapor deposition method at high productivity and low cost.

Resin product, production method for the same, and deposition method for a metallic coating

The present invention provides a metallic coating having a sheen and having a discontinuous structure at high productivity and low cost by using sputtering. A resin product includes a resin base material, and a metallic coating having a sheen and a discontinuous structure that is deposited on the resin base material so as to include a portion in which a high-formation metal that relatively readily forms a discontinuous structure when using vacuum vapor deposition is sputtered, and thereafter, a low-formation metal that does not relatively readily form a discontinuous structure when using vacuum vapor deposition is sputtered. The high-formation metal and the low-formation metal are selected from at least two species of metals whose crystal structures are identical and whose lattice constant difference is within 10%.

Resin product having a metallic coating

A paint composition for use in a resin molding product prevents the appearance of coating film sink marks caused by unevenness of the coated surface by incorporating a coloring pigment and an extender pigment into the paint composition. The coloring and extender pigments are present in the paint composition in a total pigment weight concentration (PWC) of less than 30%.

Paint composition for use with resin molding products

A glittering paint, not requiring formation of primer layer and/or clear top coat layer includes a coated film forming polymer, a glittering pigment comprising inorganic powder and a solvent, wherein the coated film forming polymer comprising a pigment carrying polymer, wherein the pigment carrying polymer has a weight average molecular weight (Mw) of at least 50,000 and a refractive index n of at least 1.48 as measured by an Abbe refractometer, the coated film forming polymer has an entire weight average molecular weight (Mw) of at least 50,000, the inorganic powder has an aspect ration of particle length or diameter to particle thickness of at least 50, and the glittering pigment content (PWC) in the coated film is 15 wt % or less.

Glittering pigment and glittering coated film

A decorative sheet is obtained by a process which comprises superimposing a reinforcing plate, a second hot melt adhesive sheet, a porous decorating sheet, a third transparent hot melt adhesive sheet, and a transparent film in sequence on a first hot melt adhesive sheet, and then subjecting the laminate to heat pressing. The decorative sheet is then inserted into the mold. A base resin is then injected onto the back side of the first adhesive sheet of the decorative sheet.

Decorative molded product and process for the production thereof

A molded article containing an outer decorative film and a support, and a method and composition for making the same are disclosed. The outer film has a decorative layer and a protective layer, the protective layer being formed from a photopolymerizable resin composition. In an uncured state, the composition includes (a) an acrylic copolymer containing a backbone and at least one side chain linked to the backbone, the at least one side group having at least one (meth)acryloyl group, the backbone having a glass transition temperature of about 40.degree. C. to about 120.degree. C. and a weight-average molecular weight of about 10,000 to about 200,000; (b) a compound other than the copolymer (a), the compound having at least three (meth)acryloyl groups; and a photopolymerization initiator. The at least one (meth)acryloyl group is preferably linked to the backbone by a reacted glycidyl group.

Molded article containing a decorative film and a process for preparing

A coated molded article including a body of an olefin resin and finish coat of an acrylic urethane resin paint, the paint includes a modified acrylic polyol resin produced by copolymerizing an acrylic resin with a polar group-introduced polyolefin and an acrylic polyol resin. Particularly, coated molded articles of an olefin resin can be used as exterior components for automobiles (e.g. side molding, bumper, wheel cap, etc,), as well as exterior components for buildings. These exterior components are required to have physical properties as article such as weather resistance, abrasion resistance and the like, while maintaining an attractive appearance.
