Definitions

• This invention has for object a method for coloring/painting objects by means of color transfer from a pre-colored-painted support film.
• the invention finds particular even if not exclusive application as a coloring and painting process for objects, in any material they are, by transfer the color/picture on said objects from a support previously colored/painted with the respective picture.
• Silkscreen process uses essentially a known screen in which the desired negative Figure/Picture in negative is preventively realized., and a doctor- blade.
• the doctor-blade passing on the screen opportunely prearranged with a color dosage, provides to distribute it uniformly, allowing the transfer of the color across the screen to the underlying object to be painted.
• the main drawbacks denoted in this solution consist firstly in that the the coloring in curved surfaces on said objects is impossible, secondly during the working in polychromy we are obliged to use one color at time increasing the costs.
• the preprinting method is disclosed by the same Applicant with the Italian patent Application No. 82544 A/88 having for object a method for painting in various colors particularly chromatic on plastic objects.
• This method suggests preventive obtainment of a cliche, and is characterized in that it comprises a basic preventively untidy series of colors.
• This basic colors being yellow, red, blue and black, and corresponding with any basic color to a cliche for the obtainment of a matrix, to be in logic sequence transferred by transfer means on a plastic object to be painted and at the end covered from a protective stratum.
• Such solution is used to decorate manually spectacle frames, by spray or by immersion. In both this solutions we have easily detaching of the color /picture applied on the object, because not well anchored.
• the third process provides the color transfer in worm condition, with a temperature of about 230°C, of pre-coiored-painted film in bobbin, which film is placed on the object to be colored and applying on the same a thermic pad (moulding shaped plate) for some seconds, this action allowing transfer the color/picture from the film on the underlying object surface.
• This solution have the same drawbacks denounced for the previous processes, and further the user is obliged to use a standard film on the market, not having the possibility to use pictures and drawings of his own creation.
• a further drawback is a limitation in great size coloring, the small size being the only one allowable.
• Scope of the present invention is to obviate the above-mentioned drawbacks.
• Figure 1 represents a view of an object to be colored/painted, namely a button.
• Figure 2 represents a view of a first phase of the transfer method.
• Figure 3 represents a successive phase following the previous one.
• Figure 4 represents a preprinted support having the same color/picture to be transferred on the object to be treated.
• the transfer support is for polychromy color transfer, this transfer support can be in plastic material, metallic or paper, preventively printed with the color-picture to be reproduced.
• the picture made on this transfer support or medium can be done with known silkscreen proceedings, or by printing or by offset, utilizing a liquid vehicle having pigment of about 10%, dry binder about 35% and solvents about 57 %.
• the pigment is an organic and inorganic pigments mix, lead
• 1 3 in temperature can be carried out independently both in oven, and to 1 4 ultraviolet rays, hot air, or in bath of chemical reagents. At the end of such 1 5 treatment, the color will be transferred from the support to the object 1 6 impregnating the surface of the last one for some tenth of millimeters.
• we 1 8 proceed as follows:
