Description

[Detailed description of the invention] The present invention relates to paint compositions.

Specifically, when writing or drawing on the surface of paper or cloth that is permeable to solvents (hereinafter simply referred to as writing, and the surface is simply referred to as the writing surface), the handwriting is caused by outline lines of a different color. The present invention relates to a paint composition to be bordered. For example, water, alcohol, vegetable oil,
It is used by adding a solvent such as a petroleum solvent and applying it using a brush.

Conventionally known paint compositions are prepared by mixing pigments, extender pigments if necessary, water-soluble thickeners, surfactants, etc. Gives only a single color of handwriting based on the pigment used.

The paint composition of the present invention differs from conventional paint compositions in that the paint composition has a combination of pigments and coloring agents such that when written on a writing surface, the periphery of the handwriting is bordered by a contour line of a different color from the central part. The object of the present invention is to provide a paint composition characterized by containing different dyes.

The paint composition of the present invention can be used for creating posters for drawing, design, etc. to be displayed at storefronts, etc., and produces a tasteful work effect. That is, the present invention relates to a paint composition characterized in that it contains a pigment, a dye whose color development is different from that of the pigment, and a sizing agent that dissolves in a solvent that can dissolve the dye.

The pigment used in the present invention is captured in the network structure of the writing surface when the paint composition is written on the writing surface, or even if the solvent diffuses into the network structure of the writing surface, the pigment is substantially absorbed. It means a metal powder pigment, a mica-based pigment, or an inorganic or organic pigment having a particle size large enough to not penetrate and diffuse, and one or more of these pigments can be used.

Therefore, it depends on the physical and chemical properties of the network structure on the writing surface, such as the constituent components of the network structure, the density, etc., or the specific gravity of the pigments contained in additives other than the essential components in the paint composition. It is generally necessary that the particle size of the pigment exhibiting the maximum frequency in the particle size distribution be at least 0.5 μm, and preferably 2 μm or more to facilitate capture in the network structure of the writing surface.

Such pigments include, for example, colored metal powders such as aluminum powder, brass powder, bronze powder, copper powder, or colored aluminum powder as metal powder pigments, mica powder, and titanium dioxide attached to the mica surface. and/or those to which iron oxide has been attached are used as pearl pigments, and scale foils obtained from the scales of hairtail fish, herring, etc. are used as inorganic or organic pigments such as carbon black, aniline black, cobalt blue, Examples include ultramarine blue, yellow iron oxide, Bengara, viridian, cadmium yellow, and Hansa yellow.

The pigment used in the present invention is usually contained in 10 to 90 parts by weight, preferably 40 to 80 parts by weight (hereinafter "parts by weight" is simply referred to as "parts") in 100 parts by weight of the paint composition. form the central part. If the amount of pigment is excessive, the fixation to the writing surface may be poor and the pigment may peel off.

Furthermore, if the amount is too small, no clear central portion will be formed on the writing surface.

The dye used in the present invention has a different color development from the pigment, and is selected from a dye that is soluble in the solvent used for writing.

When a paint composition dissolved in a solvent is written on a writing surface, the dye permeates and diffuses into the network of the writing surface together with the solvent, forming an outline around the handwriting.
As such a dye, any dye conventionally used in aqueous and oil-based writing ink compositions can be used, and examples thereof include basic dyes, acid dyes, direct dyes, and oil-soluble dyes. Note that the dissolution of the dye herein includes not only dissolution in the strict sense but also dispersion in a solvent in a state close to molecules.

The dyes used in the present invention vary depending on the color development or color density required for the outline, but usually one or more types are present in the paint composition in an amount of 0.1 to 20.0 parts, preferably 0.5 to 20.0 parts. Contains 10.0 parts.

The paste used in the present invention has the function of imparting appropriate viscosity to the paint composition when dissolved in a solvent and fixing it to the writing surface, and it is necessary to dissolve the paint composition in a solvent that dissolves the dye. be. Specifically, when a water-soluble dye is used as the dye, and when an alcohol-soluble or oil-soluble water-soluble polymer or resin is used, an alcohol-soluble or oil-soluble resin is used, respectively. The sizing agent used in the present invention is preferably 1.0 to 70.0 parts in the composition.
10.0 to 50.0 parts are contained.

If there is an excess of glue, the viscosity of the paint composition dissolved in the solvent may become too high and the dye in the composition may not penetrate into the writing surface and outline lines may not be created, or the glue may not dissolve sufficiently. may impede the adhesion to the writing surface. In addition, when the amount is too low, the fixability of the pigment to the writing surface becomes poor.

The sizing agent used in the present invention includes gum arabic, dextrin, polyvinylpyrrolidone, carboxymethyl cellulose, and water-soluble polymer or resin.
Hydroxypropyl cellulose, polyvinyl alcohol, etc. are used as alcohol-soluble resins, and polyvinyl alcohol, polyvinyl butyral, ethyl cellulose, etc. are used as oil-soluble resins.
Examples include copal resin, rosin, hydrogenated rosin ester, petroleum resin, phenolic resin, rosin-modified phenolic resin, etc., and one or more natural resins, synthetic resins, etc. that are usually used in oil-based varnishes and paints are selected. It can be used as

Furthermore, in the paint composition of the present invention, extender pigments such as calcium carbonate, bentonite, kaolin, silica, and alumina millicate, dialkyl sulfosuccinic acid ester sodium salt, and naphthalene sulfon, which are commonly used in paint compositions, may be added as necessary. Various surfactants, fragrances, etc. of anionic type such as acid soda formalin condensate or nonionic type such as polyethylene glycol lauryl ether can be added.

The extender pigment is used for the purpose of adjusting the gloss when a metal pigment is used, and is used in an amount of 0 to 5 parts in the paint composition.

In addition, surfactants are used for the purpose of improving the dispersion of pigments in paint compositions and making it easier for dyes to penetrate into the writing surface, especially when dissolved in water as a solvent. ~7.0 parts are used.

When the paint composition of the present invention is written on a writing surface, the pigment is captured by the network structure of the writing surface and its permeation and diffusion are inhibited, so that it is applied onto the writing surface precisely along the handwriting. At this time, some of the dye also forms the handwriting, but on the other hand, it also penetrates and diffuses into the network of the writing surface together with the solvent, and reaches beyond the periphery of the handwriting formed by the pigment to the outside, resulting in a color different from the handwriting. It creates a border around the handwriting to form an outline.

The paint composition of the present invention can be prepared by conventionally known methods.

For example, by using a kneader, crusher, cylindrical type, V-type mixer, etc., add pigments, dye pastes, and other additives such as surfactants as necessary simultaneously or sequentially, and mix and stir. can get.

Note that when the paint composition is prepared without adding a solvent, a powdery paint is obtained, and when a solvent is added in advance, a paste-like paint is obtained. In the latter case, heating may be performed as necessary.
