ABSTRACT:
The disclosure is of a composite lamellar pellicle for producing thermographic patterns by means of liquid crystals which are spread upon an inner sheet and sandwiched between two outer sheets both of which have adequate mechanical strength for normal handling and at least one of which is transparent, all three layers preferably being poor conductors of heat and flexible without being elastic.
