Observations of the testing of tinting strength and particle size distribution of aqueous organic pigments

Observations of the testing of tinting strength and particle size distribution of aqueous organic pigments. I. Kaiser, Willi (Hoechst A.-G., Frankfurt/Main, Ger.). Kolor. Ert., 19(4), 220-30 (Hungarian) 1977. CODEN: KOERA9. ISSN: 0023-2939. DOCUMENT TYPE: Journal CA Section: 42 (Coatings, Inks, and Related Products) A method was described that can be used for detn. of tinting strength of flexo printing inks. Color d. vs. pigment concn. curves were detd. by densitometry for Pigment Red 112 [6535-46-2] in shellac or crotonic acid-vinyl acetate copolymer [25609-89-6], applied to light paper as a 25-36-mm-thick film.

PRIORITY: EP 1995-201788 30 Jun 1995. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) The title monosheet material contains 0.02-1.0 g/m2 non-diffusible dye or pigment particles which have an no. av. particle diam. of 0.01-0.5 mm and absorb photoexposure light. The dye may be carbon black or C.I.In this experiment, several chemicals are used like 6535-46-2 Pigment Red 112. The material shows high resoln. .
