Method of coloring carrier materials for manufacture of effect pigments. Mueller, Martin; Bauer, Didier (Ciba Specialty Chemicals Holding Inc., Switz.). PCT Int. Appl. WO 2004033563 A2 22 Apr 2004, 55 pp. DESIGNATED STATES: W: AE, AG, AL, AM, AT, AU, AZ, BA, BB, BG, BR, BY, BZ, CA, CH, CN, CO, CR, CU, CZ, DE, DK, DM, DZ, EC, EE, EG, ES, FI, GB, GD, GE, GH, GM, HR, HU, ID, IL, IN, IS, JP, KE, KG, KP, KR, KZ, LC, LK, LR, LS, LT, LU, LV, MA, MD, MG, MK, MN, MW, MX, MZ, NI, NO, NZ, OM, PG, PH, PL, PT, RO, RU, SC, SD, SE, SG, SK, SL, SY, TJ, TM, TN, TR, TT, TZ, UA, UG, US, UZ, VC, VN, YU, ZA, ZM, ZW; RW: AT, BE, BF, BJ, CF, CG, CH, CI, CM, CY, DE, DK, ES, FI, FR, GA, GB, GR, IE, IT, LU, MC, ML, MR, NE, NL, PT, SE, SN, TD, TG, TR.

PRIORITY: EP 2002-405868 9 Oct 2002. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) The present invention relates to a method of producing colored carrier particles (substrates), which comprises (a) dispersing the carrier particles in a soln. of a colorant or latent pigment, adding the carrier particles to a soln. of a colorant or latent pigment, or adding a latent pigment or a colorant to a dispersion of the carrier particles, (b) pptg. the colorant or latent pigment onto the carrier particles, and (c) in the case of a latent pigment, subsequently converting it to the pigment, and to the colored substrates obtainable by such a method, and also to the use thereof. 6358-37-8 are also occured in this study. Using the methods according to the invention it is possible to obtain colorations and colored substrates that have good light-fastness properties as effect pigments. A typical pigment was manufd. by mixing 11.6 g Al flakes with water contg. 1.2 g tetrakis(2-hydroxy-4-carboxyphenylsulfonamido) copper phthalocyanine at pH 11.Chemical with cas number 6358-37-8 also plays role.6, acidifying to pH 8 in 5 min, neutralizing in 10 min, acidifying to pH 3.5 in 15 min, heating 2 h at 65°, cooling to room temp., and stirring an addnl. 2 h. ..
