Title: Record mfr. using photo-hardening lacquer - spread at low pressure onto mould and pressed with support foil
Inventor: KOOP HERMANN DIPL CHEM DR
IPC: B29C43/02
Filed: 1980-10-30
Abstract: A photo-hardening lacquer is applied at low pressure, uniformly distributed, between a mould for one face of the record and a support plate or foil which is transparent to radiation; the resultant moulding is then irradiated with light energy comprising substantially u.v. components to harden the lacquer, bonding it to the support material; the record together with the support foil is then removed from the mould and, if necessary after trimming the support foil to circular form, constitutes one-half of the record. Pref., the series of procedures is then repeated (bottom line) to form the other side of the record using a mould. Pref. support material is transparent plastics, esp. preshaped to form the record base. Pref. photo-hardening lacquer is acryl-based, more specifically methacrylate-based, or thiophene-based. It may be applied to the support at room temp. Used for the prodn. of conventional records. The method makes use of the principles adopted in the prodn. of video records using a hardening lacquer and eliminates the requirement for heavy high-pressure presses. Despite the greater coarseness of the information required in the moulding of a record and the consequent extra thickness of the lacquer coating, the procedure is satisfactory. Due to the redn. in pressure to approx. 1 atmosphere, the nickel dies used can be reduced in thickness, for example, to 100 micron or less.
