Abstract
The invention relates to laminates including at least a first resin impregnated sheet having an electroluminescent compound dispersed therein and electrical leads coupling the electroluminescent compound to a source of electrical energy. The laminate is manufactured by applying an electroluminescent compound to a first resin impregnated sheet, applying electrical leads to the first sheet for the selectively application of electrical energy and heating and pressing the first sheet.
Claims14
A decoratve laminate formed under heat and pressure to form a unitary structure, comprising:
- at least a first resin impregnated paper sheet having an electroluminescent compound dispersed therein and electrical leads coupling the electroluninescent compound and first resin impregnated paper sheet to a source of electrical energy;
- a second resin impregnated paper sheet over which the first resin impregnated paper sheet lies;
- the first resin impregnated paper sheet and the second resin impregnated paper sheet being formed under heat and pressure to form a unitary laminated mass;
- and
- further including a core layer, composed of at least one resin impregnated paper sheet, over which the first resin impregnated paper sheet and the second resin impregnated paper sheet lie, wherein the core layer includes conductive leads for attachment to a power source.
An electroluminescent decorative laminate formed in accordance with a method comprising the following steps:
- applying an electroluminescent compound to a fist resin impregnated paper sheet;
- applying electrical leads to the first resin impregnated paper sheet for the selective application of electrical energy to the elecrolmescent compound and the first resin impregnated paper sheet:
- staking a second resin impregnated paper sheet with the first resin impregnated paper sheet;
- staking a core layer, composed of at least one resin impregnated paper sheet, beneath the first resin impregnated paper sheet and the second resin impregnated paper sheet, and the core layer includes conductive leads for attachment to a power source;
- and
- heating and pressing the first resin impregnated paper sheet, the second resin impregnated paper sheet and the core layer to form a unitary laminated mass.
