Abstract: According to the embodiment of the present disclosure, an organo tin compound is represented by the following Chemical Formula 1: In Chemical Formula 1, L1 and L2 are each independently selected from an alkoxy group having 1 to 10 carbon atoms and an alkylamino group having 1 to 10 carbon atoms, R1 is a substituted or unsubstituted aryl group having 6 to 8 carbon atoms, and R2 is selected from a substituted or unsubstituted linear alkyl group having 1 to 4 carbon atoms, a branched alkyl group having 3 to 4 carbon atoms, a cycloalkyl group having 3 to 6 carbon atoms, and an allyl group having 2 to 4 carbon atoms.

Abstract: Proposed are a thermal transfer ribbon and a sticker printing method using the same, which can form not only full-color images formed by a color ink part but also points, such as pearl, fluorescent, luminous, sparkling, glass, and metal glitters. The thermal transfer ribbon includes: a color ink part having a yellow ink part (Y), a magenta ink part (M), and a cyan ink part (C); an overlay part forming an overlay layer to protect a printed surface; and at least one point ink part provided between the color ink part and the overlay part.

Abstract: Provided is a recording medium for a nail sticker and a method of manufacturing the same, and more particularly, to a recording medium and a method of manufacturing the same, which show that an ink reception layer is formed on a base of a polyurethane material so that a nail sticker can be printed using a sublimation printer. The recording medium for a nail sticker comprises: a release paper; an adhesion layer formed on the release paper; a base of a polyurethane material attached onto the adhesion layer; an undercoating layer formed on the base; and an ink reception layer formed on the undercoating layer.

Abstract: Proposed is a dye-sublimation printer, and more particularly to a dye-sublimation printer that can systematically control upward and downward movements of a pick-up roller, upward and downward movements of a platen roller, and driving of a take-up reel gear according to forward and backward movements of a slide plate.
