In formula (3), W is linked to Z, the carboxyl group is linked to R, and W represents at least one of an H atom, a substituted or unsubstituted alkyl group having 1-14 carbon atoms, an alkylene oxide group having 2-6 carbon atoms, a substituted or unsubstituted aryl group and a substituted or unsubstituted heteroaryl group having 3-14 carbon atoms.

A copolymeric pigment dispersion resin derived from isobornyl (meth)acrylate and one or more other monomers has a number average molecular weight less than about 10,000 and is derived from sufficient isobornyl (meth)acrylate so that a 60 wt. % solution of the resin in propylene glycol monomethyl ether acetate forms a clear solution when combined at room temperature with at least three times the resin weight of odorless mineral spirits. The resin may be compatibly mixed with solvent-borne coating compositions based on polar or on non-polar solvents, and can provide a single factory shader or point-of sale colorant formulation for tinting a wide range of such coating compositions.

The present disclosure relates to a composition for oil paint additive. The disclosed composition provides shorter oxidation process, has better UV resistance, is toxic free, and eliminates the need to varnish 1. In accordance with one embodiment of the present disclosure, the disclosed composition primarily comprises stand oil, drying oil, mica powder, fumed silica, Canada balsam, pulverized glass and spike oil.

A near infrared absorbing-fine-particle dispersion liquid having absorption in a near infrared region, having clear contrast, and being applicable to offset printing; a method for producing the same; an anti-counterfeit ink composition using the near infrared absorbing-fine-particle dispersion liquid; and anti-counterfeit printed matter using the near infrared absorbing-fine-particles. The near infrared absorbing-fine-particle dispersion liquid contains a solvent of one or more from vegetable oils or vegetable oil-derived compounds; near infrared absorbing-fine-particles of 2 mass % or more and 25 mass % or less, selected from one or more of hexaboride fine-particles expressed by formula XB.sub.a (where X is one or more kinds of specified elements, and 4.0a6.2); and a dispersant soluble in solvent and having a fatty acid in its structure, where the viscosity is 180 mPa.Math.s or less. The anti-counterfeit printed matter is excellent in anti-counterfeit effect due to the near infrared ab sorbing-fine-particles.

An inorganic particle dispersion having high spinnability is provided. The inorganic particle dispersion according to one embodiment includes an inorganic powder, hydrophilic fumed silica, and a resin having a hydroxyl group.

The method prepares an aqueous pigment dispersion. The method includes the following steps: providing a silica liquid including a hydrophilic fumed silica, potassium hydroxide and ion exchanged water; providing a styrene-acrylic acid copolymer obtained by copolymerizing monomers including a styrene monomer at an amount of 50 to 90 mass %; providing an aqueous medium; mixing a pigment with the styrene-acrylic acid copolymer and the aqueous medium to prepare a first mixture; and subsequently mixing the first mixture with the silica liquid to prepare the aqueous pigment dispersion.

This invention provides a polymer thick film dielectric paste composition, comprising a mixture of titanium dioxide and boron nitride powders, a resin blend of polyol and phenoxy resin, one or more additives selected from the group consisting of a linear aliphatic polyester, a block copolymer, a blocked aliphatic polyisocyanate, and a wetting and dispersing agent, and one or more polar, aprotic solvents. The paste composition may be used to form polymer thick film dielectric layers in electrical circuits subject to thermoforming and in articles requiring stretchable dielectric layers such as wearables.

3D printable inks are disclosed which include one-part room temperature vulcanized (RTV) silicone and carbon particles such as carbon nanotubes (CNTs). Butyl acetate may be used as a solvent to disperse the CNTs in the silicone in the ink precursor. The one-part nature of the inks (i) enables to print without prior mixing and cures under ambient conditions; (ii) allows directly dispensing 100 ?m resolution printability on nonpolar and polar substrates; and (iii) forms both self-supporting and high-aspect-ratio structures, key aspects in additive biomanufacturing that eliminate the need for sacrificial layers; and (iv) lends efficient, reproducible, and highly sensitive responses to various tensile and compressive stimuli. The high electrical and thermal conductivity of the CNT-silicone composite is further extended to facilitate use as a flexible and stretchable heating element, with applications in body temperature regulation, water distillation, and a dual temperature sensor and Joule heating source, for example.
