Definitions

• the invention here disclosed relates to a transparent transfer film, from printed films meant for thermal transfer of the images which they bear, particularly in shoes.
• This invention is characterised by a special construction of the transfer film from several plastic materials, preferably high-density polyethylene, which has the advantage of lower production and application costs, the latter due to the ease and speed in placing because of its transparent nature.
• Thermal transfer films for all types of prints are widely known and used for a large variety of consumer products, so that no further explanation is required, as the term "transfer film” has even extended beyond technical language into everyday speech.
• the invention object of the present memory relates to a transparent transfer film, from among printed films such as with inks with pigments mixed with grease and linseed oil, or others with several copolymers which carry printing inks and pastes, all of these suitable for thermal transfer from the paper of the images they bear.
• This invention applies particularly to shoes, although the film disclosed can be used in many other applications, such as leather goods or the textile industry, where centering an image is required or desired.
• This invention is characterised by a particular construction of the transfer film, from several plastic materials which can withstand changing temperatures without wrinkling, which do not exceed or barely exceed 120 °C, as well as having the thickness required for each working temperature range, preferably high density plastics such as polyethylene.
• the film receives the ink by serigraphy, although other printing processes are not discarded, and the ink is of the water ink type.
• the printed film is simply air dried, placed on conventional drying racks for serigraphy material.
• the material of the film may or may not be recoverable for recycling in further applications, as in the extreme limit it may wrinkle, in which case re-use is not recommended as it is no longer flat, with the used product simply recycled as chaff.
• the present invention relates to a transparent transfer film from among printed films meant for thermal transfer of the images they bear, essentially characterised in that a biodegradable material is used, not affecting the ecological balance and with lower production costs than conventional paper, with no limit to the number of colours which it may receive, and furthermore allowing to centre the image, thus saving adjustment time and costs when placing it, by means of a special construction of the transfer film using several plastic materials with suitable transparency which may withstand without wrinkling temperatures of at most 120 °C or not much higher, as well as made with the thickness required for each working temperature range, preferably from high density plastic materials with a high molecular mass, such as polyethylene.
• the film preferably receives the ink by serigraphy, although other printing processes are not discarded and the printed film is simply air dried, placed on conventional drying racks for serigraphy material.
• the material of the film may be recovered for recycling in further applications or as chaff.
• composition employed can vary, with two having been chosen:
• Base V6 from Navi, S.L. also vinyl based, specifically polyvinyl acetate.
• Pigments of either ink are from Corec S.L..
• the common support for both cases is a polyethylene known as HE-6991, with antioxidant, from Thermoplast S.L., of high density and high molecular mass and suitable transparency for the purposes of this invention.
