Method for producing micron-resolution coloured images embedded in a very robust, very durable medium

摘要

A method for producing a colored or fluorescent substrate with a view to formation of a colored or fluorescent image including the formation. The method defines on a substrate of a colored or fluorescent matrix, pixels of at least two different colors, wherein each pixel forms a filter for a given color. At least one filter is an interferential filter or a filter obtained with colored or fluorescent particles.

1. A method of producing a color image on or in a substrate, comprising:
producing a colored or fluorescent substrate for purposes of forming a colored or fluorescent image, and before formation of such an image, the production of the colored or fluorescent substrate including:
forming, on a substrate, a colored or fluorescent matrix, defining pixels of at least two different colors, wherein each pixel forms a filter for a given color, andwherein at least one filter is obtained with colored or fluorescent particles, of mineral or organic type, formed using surface plasmon effect particles of Au, Ag or Pt type, or using organic molecules included in a mineral matrix; and producing the image, fixed directly on or in the colored or fluorescent substrate by performing a lithography process to partially mask at least one color of the matrix.
