Method for producing decorative elements, particularly insignia

摘要

The method comprises the steps of: preparing a multiple-layer film (10) comprising a first transparent protective layer (12), a second decorative layer (14) containing at least one pigment made of metal having a melting point below 250° C., and a third supporting layer (16) of thermoformable plastic material, at least a portion (13) of the surface of the first layer (12) opposite the second layer (14) being screen-printed with a polyurethane and/or acrylic based ink; thermoforming the film (10) at a temperature in the range from 130 to 180° C. and at a pressure in the range from 10 to 20 bar, in such a way as to form at least one recess (28) therein; pouring into the recess a thermosetting resin (30) which adheres to the third layer (16) of the film (10); making a covering sheet (32) adhere to the third layer (16) of the film (10) so as to enclose the poured resin (30), which undergoes a hardening process; and cutting the film (10) around the recess (28), thus producing a stratified decorative element comprising a portion of the film (10), a layer of resin (30) and a portion of the sheet (32).

1. Method for producing one or more decorative elements, particularly insignia (38), comprising the steps of:
preparing a multiple-layer film (10) comprising a first transparent protective layer (12), a second decorative layer (14) containing at least one pigment made of metal having a melting point below 250° C., and a third supporting layer (16) of thermoformable plastic material, at least a portion (13) of the surface of the first layer (12) opposite the second layer (14) being screen-printed with a polyurethane and/or acrylic based ink, thermoforming said multiple-layer film (10) at a temperature in the range 130 to 180° C. and a pressure in the range 10 to 20 bar, so as to form at least one recess (28) therein,
pouring into said at least one recess (28) a thermosetting resin (30) which adheres to the third layer (16) of the film (10), making a covering sheet (32) adhere to the third layer (16) of the film (10) so as to enclose the poured resin (30), which undergoes a hardening process, and cutting the film (10) around said at least one recess (28), thus producing a stratified decorative element comprising a portion of said film (10), a layer of resin (30) and a portion of said sheet (32).
