It should be noted that the present invention is the following discovery based on inventor and completed：
In allochroic paint, the selection of resin has highly important influence to the colour saturation and lustrous surface of allochroic paint,
If with the resin modulation allochroic paint in common coating coating can be caused to be too high to use because of viscosity.Therefore, modulation applies
The dosage of resin can only be reduced during material, so that dope viscosity reduces.Consequence caused by so is, after coating is dried, due to
Resin content is seldom, causes pigment excessive, and resin is not enough to the space filled and led up between pigment so that coating surface bumps are not
It is flat, it is lackluster, and easy efflorescence, so as to form diffusing reflection to light.So coating performance colour saturation is low and gray scale is high, for black
For color coating, it appears ash is without black.
In view of this, inventor has found that the viscosity of thermosetting acrylic resin emulsion is appropriate, resulting by many experiments
Allochroic paint colour saturation and lustrous surface it is higher.Further, inventor has found, the component of allochroic paint, such as feels
Proportioning between the species of light colour-changing pigment, the species of wetting dispersing agent and each component etc. can influence the product of allochroic paint
Property.And then inventor obtains preferable allochroic paint component and its proportioning, on this condition resulting change by many experiments
Color coating has at least one of following advantages：Strong to adhesive force such as glass, metal, ceramics, stability is strong, and the paint film of formation is saturating
Bright property is good, glossiness is high, richness is excellent, protect light and guarantor's color effect is good.
Therefore, in one aspect of the invention, the present invention proposes a kind of allochroic paint.According to an embodiment of the invention,
