Abstract

The current double-shot molding approach to introduce legend on key-buttons has lent itself to high volume production. Meeting the rapid escalation of customer requirements for personalized keyboard labelling by utilizing the conventional two-shot molding concept cannot be justified due to the high cost of mold fabrication for low volume keybutton production as well as the turnaround time required by customers.

Keybutton Personalization by Actinic Irradiation of Photosensitive Coatings

The current double-shot molding approach to introduce legend on key- buttons has lent itself to high volume production. Meeting the rapid escalation of customer requirements for personalized keyboard labelling by utilizing the conventional two-shot molding concept cannot be justified due to the high cost of mold fabrication for low volume keybutton production as well as the turnaround time required by customers.

A low cost manufacturing process for generating nomenclature on keybuttons on a personalized basis is described, wherein photosensitive polymers with metal chelates or monomers are exposed to actinic radiation. The finished keybuttons, resulting from the subject manufacturing process for introducing legend onto keyboards, are made in accordance with the following guidelines 1) Keybutton surfaces are fabricated with a mat or dull finish. 2) Personalization is performed at the keybutton assembly area. 3) Optically dense, high contrast, and good resolution of characters can be achieved by available metal chelates. 4) Nonsmearing characters of archival quality are provided. 5) Color capability and nontoxic.

The process of generating legend by actinic irradiation of dye containing photopolymers or metal chelates is as follows. Color-containing photosensitive materials/coatings are subjected to computer-controlled actinic radiation to generate desired patterns or characters. The process...
