Manufacturing method of deco-film for housing of smart phone thermal transfer-ink ribbon having patterned layer and the deco-film for housing of smart phone manufactured by the same

摘要

The present invention comprises the steps of sequentially laminating a release layer, a first primer layer, a pattern printing layer, and a second primer layer to prepare a thermal transfer pattern ink ribbon including a thermal transfer pattern ink film having a total thickness of 1 to 2 μm; Positioning the thermal transfer pattern ink ribbon on the smartphone housing substrate so that the second primer layer of the thermal transfer pattern ink film faces the smartphone housing substrate; By performing a thermal transfer process using a thermal transfer head to which a voltage of 200 to 210 V is applied at a pulse rate per second (pps) of 90 to 105, a second primer layer, a pattern printing layer on the smartphone housing substrate And forming a first primer layer, wherein the substrate for the smartphone housing is a polyester substrate, and the second primer layer includes a vinyl polysiloxane resin, and the substrate for the smartphone housing and the second primer A method of manufacturing a deco film for a smartphone housing using a pattern ink ribbon for thermal transfer that can improve the interface properties between the layers, simplifying the process, reducing the process time, and improving the aesthetics and visibility, and the smart manufactured thereby. It relates to a deco film for phone housing.
