    Abstract: The purpose of the present invention is to provide an oil-in-water emulsion composition exhibiting high UV-protective capabilities with which it is possible to uniformly and stably disperse a hydrophobized metal oxide into an inner phase (oil phase) without detracting from the inherent fresh sensation on use of an oil-in-water emulsion composition even when a high amount of the hydrophobized metal oxide is compounded therewith. In summary, the present invention is an oil-in-water emulsion composition characterized by including (A) 0.1-5 mass % of polyether-modified silicone having an HLB (Si) of 5-14, (B) one or more hydrophilic thickeners, (C) a metal oxide hydrophobized by an agent other than metal soap, and (D) nonvolatile oil other than silicone oil, the (C) hydrophobized metal oxide being present in the inner phase.

  • Patent number: 10689534
    Abstract: The present invention provides an aqueous dry-erasable ink or marking composition, which could be applied to both porous and non-porous surfaces and erasable from both porous and non-porous surfaces or marking substrates. The present invention further provides erasure of mark made by the ink composition from such porous and non-porous substrate, which is achieved by a cloth or the like, without requiring rubbing by conventional erasers. The ink composition comprises water, composite pigment, one or more rheology additive, one or more wetting agent, one or more water-soluble resin, pH adjuster and one or more biocide. The composite pigment is a compound of polymer resin and colored pigment at a weight ratio from 10/90 to 97/3.

  • Patent number: 10619063
    Abstract: A water-based pigment type inkjet ink composition contains: a pigment whose surface is formed as a resin layer produced by crosslinking, using a crosslinking agent having two or more functionalities, an alkali-soluble resin whose acid value is 40 to 300 KOHmg/g, and 50 to 90% of whose acid groups have been neutralized by a basic compound; a water-soluble organic solvent; and a surface-active agent; wherein the alkali-soluble resin is such that lauryl(meth)acrylate is contained in the alkali-soluble resin, as its constitutional unit monomer, by 20 to 40 percent by mass relative to the total quantity of monomers. The water-based pigment type inkjet ink composition can exhibit good printability characteristics as well as a wide color gamut and can also offer excellent storage stability.
