A METHOD OF DEPOSITING AN ABRASION-RESISTANT LAYER ONTO AN ELECTROLUMINESCENT PLASTIC WINDOW

摘要

A method for applying an abrasion resistant layer (60) via a vacuum deposition technique to a plastic automotive window (100) is provided. The plastic automotive window (100) includes a plastic panel (30), an electroluminescent layer (40), and a weatherable layer (50). A first abrasion resistant sub-layer (63) is then deposed on top of the weatherable layer (50), and a second abrasion resistant sub-layer (66) is then applied onto the first abrasion resistant sub-layer (63). The deposition of the abrasion resistant sub-layers (63, 66) is carried out under controlled temperature conditions that reduce adhesion loss within the electroluminescent layer (40) and maintains the electroluminescent functionality of that layer (40).
