Abstract: The compsn. contains a dispersion medium (I), consisting mainly of surfacant, with fluoro-resin particles (II) and pigment particles (III) dispersed in Ia. USE/ADVANTAGE - The compsn. is used as the undercoat of a system for coating mouldings (opt. with a finely roughened surface) overall or in a pattern, the top coat contg. (II) but no (III) or adhesive. It is useful for producing coatings or uniform colour or displays e.g. scales, patterns or lettering on metals, before or after moulding to containers. In an example, a finely etched Al alloy plate was given a 20 micron primer coat with a comspn. contg. 60 (wt)% PTFE, 3% polyamide-imide, 6% surfactant and 31% water (which was baked for 5 mins, at 420 deg. C. It was then screen printed with a compsn. contg. 26.25g PFA (TFE-perfluoro(alkylvinyl ether) copolymer) as 5 micron or coarser particles, 11.25 g PFE as 1 micron or finer particles, (A) 38.75, (B) 438.75 g nonionic surfactant and 11.25 g water and 12.5 g TiO2, which was baked for 10 mins, at 400 deg. C. The amt. of blurring of the edge of the letters was (A) none, (B) significant; flaking (A, B) none; and flow (A,B) no variation in film thickness

Abstract: PURPOSE:To provide the subject brilliant composition capable of displaying scales, patterns. letters, etc., without being stamped, not abraded, and exhibiting a sufficient adhesive force to resins by compounding a dispersant comprising a surfactant with fluororesin particles and pigment particles. CONSTITUTION:The objective composition is characterized by compounding a dispersant consisting mainly of a surfactant (preferably a nonionic surfactant such as polyethylene octylphenyl ether) with fluororesin particles (preferably the particles of a thermally meltable fluororesin such as PFA or PEP) and pigment particles (preferably titanium oxide). The composition is coated uniformly or in the form of scales, patterns, letters, etc., on the fluororesin layer of a fluoro resin-coated article, and the coated article is further coated with a fluororesin composition not containing a pigment, an adhesive, etc., to obtain the coated article.

Abstract: A fluororesin-coated material having markings indicated thereon is disclosed, which material comprises (1) a substrate having coated thereon a fluororesin composition comprising a high-molecular weight material having a benzene ring and at least one of a nitrogen atom, a sulfur atom and a carbonyl group in the main chain thereof, or (2) a substrate having coated thereon the high-molecular weight material, and further having coated on the high-molecular weight material a fluororesin composition. The markings are indicated on the coated material by irradiating the coated surface of the coated material with electromagnetic waves having a wavelength of 600 nm or less to thereby cause a change in the color of the high-molecular weight material at irradiated parts and provide a difference in color between the irradiated parts and unirradiated parts.
