Abstract
The utility model discloses leather with variable surface color, mainly comprising leather whose outer surface is coated with a variable color material layer. As the outer surface of the leather with the variable surface color provided by the utility model is coated with the variable color material layer, the color of the leather can be converted along with the change of the temperature or the ultraviolet light, and thus, the leather is more shapely and novel. In addition, the variety of the leather material is increased.
Description
Technical field
The utility model relates to a kind of leather, and the color of this leather outside surface can present variation under certain condition.
Background technology
The leather of Xiao Shouing in the market, its outside surface color generally is that fixed is a kind of, can be along with environment transition changes colour.
Summary of the invention
The purpose of this utility model provides the transformable leather of a kind of surface color, and the surface color of this leather can vary with temperature or ultraviolet irradiation conversion color.
For this reason, the transformable leather of the surface color that the utility model provides mainly comprises leather, and the outside surface of leather is coated with the chromic material layer.
Because the outside surface of the transformable leather of surface color that the utility model provides is coated with the chromic material layer, therefore the color of leather can the conversion with the variation of temperature or UV light, make the outward appearance of leather more beautiful, novel, also enriched the kind of leather fabric in addition.
Description of drawings
It in the accompanying drawing structural profile synoptic diagram that has the leather of chromic material layer.
In the accompanying drawing: 1, leather, 2, the chromic material layer.
Embodiment
As shown in the figure, the transformable leather of the utility model surface color mainly comprises leather 1, leather generally can be divided into leatheroid, corium and transfer-coating leather, the outside surface of leather 1 is coated with chromic material layer 2, and chromic material layer 2 can be organic heat-sensitive variable colour dye coating or organic photochromic dye coating or organic photochromic coat of colo(u)r; Above-mentioned chromic material layer is to be applied by the mixture of Polyurethane and changeable colour dyestuff or pigment to form, it is a kind of raw material commonly used in the leather industry that Polyurethane can be called the PU resin again, generally is exactly the mixture of Polyurethane and organic photochromic dyestuff or organic photochromic pigment or organic heat-sensitive variable colour dyestuff specific to organic heat-sensitive variable colour dye coating and organic photochromic dye coating or organic photochromic coat of colo(u)r.
In the present embodiment, the making of above-mentioned organic heat-sensitive variable colour dyestuff is to adopt microcapsulary that the heat-sensitive variable colour raw material packet is wrapped in the capsule, capsular particle diameter generally is the 1-10 micron, the heat-sensitive variable colour raw material of capsule is by leuco dye, developer and sensitizing agent three form, leuco dye is some materials that can develop the color in conjunction with proton, for example interior lipid, indoles, compounds such as penta auramine class, leuco dye is conduct power supply subdivision in the variable color system, Viola crystallina lactones for example, Viola crystallina lactones itself is colourless, produces the purple compound as parent by molecular transposition.Developer is a kind of acid compound of releasing that discharges proton, as phenols, carboxylic-acid, benzotriazole and halohydrin etc., is the compound that attracts electronics.Still be example with the Viola crystallina lactones, leuco dye Viola crystallina lactones and developer is together encapsulated together with non-volatility, hydrophobic organic solvent, when temperature variation, developer can provide a proton to leuco dye Viola crystallina lactones, form the Viola crystallina of purple through molecular transposition, perhaps the Viola crystallina by purple reverts to colourless Viola crystallina lactones, and color and luster is changed between colourless and purple.
Organic photochromic dyestuff and organic photochromic pigment adopt microcapsulary equally, organic photochromic dyestuff or organic photochromic pigment generally adopt spiro-pyrans compounds (spiro-pyran), spirooxazine (spiro oxazone) class dyestuff and triarylmethane dyes, this class dyestuff was colourless originally, produces photolysis (photolysis) and become coloured under 350-400 nanometer ultraviolet ray irradiation.General spiro-pyrans compounds can decompose under ultraviolet ray is shone repeatedly, but spirooxazine (spiro oxazone) class dyestuff and triarylmethane dyes have resistance.In capsule, capsular particle diameter generally is the 1-10 micron with above-mentioned coating dye, and its light fastness of machine photochromic dyes after coating with microcapsule improves greatly.Organic photochromic dyestuff or organic photochromic pigment mainly comprise four primitive colour at present: purple, yellow, blueness and red, the original texture that these four kinds of light become dyestuff is closed-loop type, promptly be imprinted on the leather lackluster, when under ultraviolet light irradiation, becoming purple, blueness, yellow and red.
Above-mentioned organic heat-sensitive variable colour dyestuff, organic photochromic dyestuff and organic photochromic pigment all are the products that had occurred on the market, still do not have at present but use these raw materials on the leather and how to use on the leather.
Its variable color process of the transformable leather of above-mentioned so-called surface color mainly is: 1, when leather surface applies the mixture of organic heat-sensitive variable colour dyestuff and Polyurethane, organic heat-sensitive variable colour dyestuff with temperature in a coloured and colourless conversion, organic heat-sensitive variable colour dyestuff is colored state under the general state, organic heat-sensitive variable colour dyestuff becomes colourless when temperature raises, and then exposing the original background color of leather, organic heat-sensitive variable colour dyestuff color occurs again on the basis of background color when temperature reduces.2, when leather surface applies the mixture of organic photochromic dyes or organic photochromic pigment and Polyurethane, organic photochromic dyestuff or organic photochromic pigment are not colourless when leather surface is subjected to ultraviolet irradiation, leather presents its background color, reveals color when being subjected to uviolizing.
Claims (4)
1, the transformable leather of a kind of surface color mainly comprises leather (1), it is characterized in that: the outside surface of leather (1) is coated with chromic material layer (2).
2, the transformable leather of surface color according to claim 1 is characterized in that: described chromic material layer (2) is organic heat-sensitive variable colour dye coating or organic photochromic dye coating or organic photochromic coat of colo(u)r.
