A method of manufacturing a resin formed product having a leather grain includes: a 3D printing step of inputting printing data to a 3D printer, and printing an intermediate product having an intermediate grain that is a base of the leather grain; and a post processing step of obtaining the resin formed product, which is a finished product, by carrying out post processing on the intermediate product printed in the 3D printing step. A grain height in input data, which is the printing data inputted in the 3D printing step, is greater than or equal to 120% of a stacking pitch in the 3D printing step.

A method for producing a resin sintered bodyby applying an inkto thermoplastic resin powderand sintering the powder, the method including the step of immersing an intermediate resin sintered body, which has an unevenly colored region on the surface thereof and the whole of which has been already sintered, in a surface treatment liquid containing sulfuric acid and chromic anhydride, in which the concentration of chromic anhydride is 300 g/L or more, for 5 minutes or longer. When producing a resin sintered body by sintering thermoplastic resin powder, the surface of the resin sintered body can be evenly and sufficiently colored to an extent required without an unevenly colored region on the surface thereof, and also the surface of the resin sintered body can have a good appearance and smoothness.

A rustproofing composition has superior properties satisfying rustproofing quality requirements and workability requirements for car underbodies, parts around tires, parts with pockets, plate-bonded parts or the like of car bodies, and containing volatile organic solvent of 20 mass % or less. In a rustproofing composition containing UV curable resin and photopolymerizing initiator and at least one of rustproofing oil and rustproofing wax, the content of nonvolatile component at 105&#xb0; C. for 3 hours in the rustproofing oil and rustproofing wax is 80 mass % or more, the UV curable resin and photopolymerizing initiator are dissolved or dispersed in the rustproofing oil and rustproofing wax, and the UV curable resin is contained at 0.3 to 10 weight % to the total weight of the composition.

Rustproofing composition

A silver alloy plating bath and a method of forming a silver alloy film by using the silver alloy plating bath and by performing displacement plating on surfaces of a more base metal than silver, the silver alloy plating bath including Ag ions and at least one or more metal ions of Pd ions, Pt ions, Au ions and Rh ions, a concentration of the Ag ions and the metal ion or ions being 0.001 to 0.01 mol/l, a mol ratio of the metal ion or ions to the Ag ions being 1:0.01 to 0.1.

The present invention provides a process for forming a multilayer film, which comprises: applying a cationic electrocoating (A) and an intermediate coating (B) in this order, followed by heat-curing, applying thereon a coloring base coating (C) capable of forming a colored film having a value of N 7 to N 9 in Munsell's color system, applying, without curing the coloring base coating (C) applied above, an iridescent base coating (D) containing a scaly mica powder coated with titanium oxide, followed by preliminary drying at 50.degree.-100.degree. C., and applying a clear coating (E), followed by heating to subject the films of the coatings (C), (D) and (E) simultaneously to crosslinking and curing, wherein the coloring base coating (C) and the iridescent base coating (D) are each a thermosetting aqueous coating containing, as vehicle components, an acrylic resin emulsion (a), a urethane resin emulsion (b) and a crosslinking agent (c). The process can form a multilayer film superior in iridescence feeling, depth feeling, smoothness, distinctness of image gloss, etc. and is suitably used for coating of, in particular, automobile body panel.
