Color-developing printing ink

Color-developing printing ink. Miyamoto, Akio; Matsukawa, Hiroharu (Fuji Photo Film Co., Ltd., Japan). Ger. Offen. DE 2722573 1 Dec 1977, 24 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C09D011-02. PRIORITY: JP 76-57671 19 May 1976. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Section cross-reference(s): 74 Solvent-free printing ink, that forms a haze-free color on colorless dye-precursor-contg. paper when exposed to UV light, contains a photopolymerizable compd., an acidic electron acceptor compd., and a white inorg. pigment, and can be used in copying processes. Thus, a mixt. contg. trimethylolpropane triacrylate [15625-89-5] 70, ketone resin (Hilak 111) 30, and p-benzoquinone 0.5 parts was heated at 115° to form a homogeneous coating mixt. with viscosity 300 cP (25°). This coating mixt. was mixed (60 parts) with Japanese acid clay 50, dipenterythritol pentaacrylate [60506-81-2] 10, N,N-4-dimethylaminobenzophenone 5, and benzophenone 5 parts and kneaded in a 3-roll mill to give a color-developing printing ink. Paper contg. 6 g/m2 microcapsules of a color-forming oil comprising 2.5 parts crystal violet lactone and 2.0 parts benzoyl-leuco-methylene glue in 4 parts diisopropylbiphenyl and 1 part kerosine was printed in a relief printing machine with 5.0 g/m2 above prepd. ink and exposed to a 2-kW UV lamp 5 cm from the printed surface to give a haze-free color on the paper, whereas a hazy color was formed on the paper when a color-developing printing ink contg. Japanese acid clay, nitrocellulose, EtOAc, BuOAc, and EtOH was used.

Coating materials having good adhesion

Coating materials having good adhesion. (Mitsui Toatsu Chemicals, Inc., Japan). Jpn. Kokai Tokkyo Koho JP 59204624 A2 20 Nov 1984 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08J007-04; C09D003-727; C09D005-00. ICA: C08F002-48; C08F220-28; C08F299-06. APPLICATION: JP 83-78281 6 May 1983. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Coating materials having good adhesion are composed of 100 parts (70-97):(3-30) mixt. of RCH2C(CH2R1)(CH2R2)CH2[OCH2C(CH2R3)(C2R4)CH2]nR5 (33 of R-R5 are CH2:CHCO2 while the others OH; n 1-5) and polyfunctional acrylate having 32 urethane bonds and 0.1-10 parts photosensitizer. The materials are esp. useful for coating polypropylene [9003-07-0] moldings and films. Thus, a coating material contg. dipentaerythritol pentaacrylate [60506-81-2] 75, Darocur 1173 [7473-98-5] (photosensitizer) 3.0, and a polyfunctional acrylate obtained from Olester NP-1000 (hexamethyene diisocyanate-H2O adduct) and hydroxypropyl acrylate 29.9 parts were applied to a Noblen BJHH-M molding and UV-irradiated to give a cured film showing excellent adhesion, hardness, and weatherability.
