Problems solved by technology

[0006] 1. Its temperature resistance is poor
When the full-transfer film is heat transfer hot stamping, the temperature reaches about 130°C. At such a high temperature, the incompletely reacted main agent and curing agent will further participate in the reaction, causing the softening and migration of the colored layer, making the full-transfer film The gloss is greatly reduced, and even cause serious loss of light
[0007] 2. Its solvent resistance is weak
When coating the back glue solution, the solvent in the adhesive can easily seep through the aluminum layer and erode the coating of the colored layer and the protective layer. If the solvent resistance of the colored layer is weak, the solvent will cause great corrosion to the colored layer. As a result, the color floating and blooming of the full transfer film will be caused, which will seriously affect the surface effect of the transfer skin.
[0008] 3. It has some difficulty in compatibility with dyes
Seriously affect the surface color effect of the full transfer film
[0009] 4. There are some problems with its bonding force with the aluminum layer
In the actual production and application process, the separation of the aluminum layer and the colored layer often occurs

Abstract

The invention discloses a coloring paint developed for a full-revolving leather film. The paint consists of the components (calculated by weight percent): host crystal (20-50), polyisocyanate resin solidifying agent (10-30), nitro cellulose resin accelerator (30-60), dye (0-10), paint assistant (1-5) and diluent (40-70). The host crystal is acrylic resin or alkyd resin or the mixture of acrylic resin and alkyd resin; the acrylic resin is hydroxyl acrylic resin, and the alkyd resin is alkyd resin with hydroxyl value and acid value. The invention has excellent temperature resisting and solvent causticity resisting performances, sound compatibility with dyes, strong bonding with the aluminum-layer, sound luster flamboyance and color fastness.

Description

technical field [0001] The invention relates to a colored layer paint, which belongs to a two-component polyurethane paint, in particular to a colored layer paint for leather full transfer film and a preparation method thereof. Background technique [0002] Leather full transfer film is also called leather hot stamping film, which is the abbreviation of full transfer hot stamping film for leather or full transfer hot stamping film. The full transfer film has a total of six layers, which are PET film, release agent, protective layer, coloring layer, aluminum layer and adhesive layer (as shown in Figure 1). [0003] The leather transfer film is hot-bonded with artificial leather, PU leather and genuine leather by heating and pressing, and the PET film on the surface is peeled off at the same time, so that the coating or pattern on the PET film is completely transferred to the leather surface. The transfer film is combined with the leather by hot pressing to form a transfer le...
