example 1

[0059] Example 1: Preparation of polymer-coated aluminum substrates by ATPR

[0060] Take 4.8 kg of lenticular aluminum pigment SSP-695 from Silberline Mfg. Company with a solid content of 75.68%, and add 11.64 kg of glycol ether PM acetate to a 20-liter reaction flask. The mixture was stirred until homogeneous, then heated to 80°C. Another 16 ml of ATRP initiator 3-(trimethylsilylpropyl)-2-bromo-2-methylpropionate was added. After reacting at 80°C for 6 hours, it was cooled to room temperature and filtered to obtain a solid. The solids content of the final product was 64.56% by weight.

[0061] Get above-mentioned fixed product 30.8 grams of initiator, be dispersed in the 310ml glycol ether PM acetate that is contained in the 500ml reaction bottle. 80 ml of N,N-dimethylaminoethyl methacrylate (DMAEMA) was added with moderate stirring. The reaction bottle was sealed, and high-purity nitrogen gas was introduced from the bottom of the bottle to make the system in an inert at...

[0064] Example 2: Preparation of green aluminum color system

[0065] 4.35 grams of the polymer-coated aluminum pigment prepared in Example 1 was dispersed into a 40 ml vial containing 15.0 grams of NMP. Another 0.40 g of phthalocyanine green-pigment green 7 (PG7) solid dispersion (40% by weight of pigment particles dispersed in polyvinyl chloride / polyvinyl acetate copolymer) was dispersed into 5.0 g of NMP. This PG7 dispersion was added to the previous aluminum pigment dispersion, followed by 4.0 grams of a 4% allyl bromide solution in NMP. The resulting mixture was stirred at room temperature for 15 minutes and then warmed to 90°C over about 30 minutes. Stir for a further 15 minutes at 90°C, then cool to room temperature. The solid obtained by centrifugation was redispersed twice in NMP and centrifuged again, and the supernatant after each centrifugation was only very light green, while the solid sediment was bright dark green.

[0066] Example 3: Preparation of blue aluminum color system

[0067] 4.35 grams of the polymer-coated aluminum pigment prepared in Example 1 was dispersed into a 40 ml vial containing 15.0 grams of NMP. Another 0.40 g of phthalocyanine blue-pigment blue 15:4 (PB15:4) solid dispersion (40% by weight of pigment dispersed in polyvinyl chloride / polyvinyl acetate copolymer) was dispersed into 5.0 g of NMP. This PB15:4 dispersion was added to the previous aluminum pigment dispersion, followed by 4.0 grams of a 4% allyl bromide solution in NMP. The resulting mixture was stirred at room temperature for 15 minutes and then warmed to 90°C over about 30 minutes. Stir for a further 15 minutes at 90°C, then cool to room temperature. The solids obtained by centrifugation were redispersed twice in NMP and centrifuged again, and the supernatant after each centrifugation was only very light blue, while the solid sediment was bright dark blue.

Abstract

The present invention discloses a color system comprising a coating substrate and color pigments adhered to the coating substrate and a method for producing the color system. The method of the present invention effectively adheres the color pigment to the coating substrate. The resulting color system avoids the problem of separation between the color pigment and the coating matrix during coating application. Colored metallic paints / inks can be prepared by mixing a color pigment solution with a coating matrix solution. The obtained color system has bright color and strong metallic luster.

Description

technical field [0001] The present invention relates generally to coated substrates and systems comprising the coated substrates, and more particularly to color systems comprising the coated substrates. Background technique [0002] Aluminum pigments are widely used for metallic effects in paints, inks, plastics and cosmetics. In order to obtain colorful metallic effects, aluminum pigments are generally used in combination with colored pigments. [0003] Colored metallic effects can be achieved by multi-layer methods during coating construction. In this method, a coat of paint / ink containing metallic pigments is applied to the substrate followed by a coat of colored pigments. Although bright colored metallic effects can be achieved with multi-layer methods, such methods are often accompanied by higher production costs because auxiliary equipment is required to complete the additional production steps. Additionally, the plethora of application steps limits product turnarou...
