The invention relates to a process for producing a PET
laser transfer membrane. A PET membrane is used as a
basement transfer membrane, and
laser transfer
pigment is coated and spread on the PET membrane. The method includes the following steps: a
laser transfer
pigment is coated and spread on the PET
basement transfer membrane by an anilox roll at one step to form a
coating layer, and a precoating membrane can be formed after the operation of
drying is carried out; the precoating membrane is processed by the operation of laser mould pressing, and interference figures on a laser slab are printed on the
coating layer of the precoating membrane by heat pressing so as to form a mould pressing membrane; and aluminum is coated on the mould pressing membrane, an aluminum layer is formed on an
information layer, and the PET laser transfer membrane can be prepared, wherein the
pigment includes
thermoplastic acroid resin and
cellulose acetate. The process has the advantages that the special singly coated laser transfer pigment and the unique manufacture
process control are selected, and the entire process is simple, novel, stable and reliable. As the laser mould pressing transfer
coating layer has the properties of easy mould pressing, favorable stripping, and the like, the operation of coating just needs to be carried out for one time, and therefore the production efficiency can be greatly improved. After being transferred and stripped, the aluminum
coated membrane can be recycled to be repeatedly used for many times, and therefore cost can be greatly reduced; and the PET laser transfer membrane is the
environmentally friendly anti-counterfeit laser material for packaging and printing.
