Beschreibung
Zusammenfassung:	This invention concerns a polymer coating composition for use as non-focal optical power limiting dye containing polymeric materials. This composition contains: (1) one or more Modified Polymers comprising a Polymer, such as a hyperbranched polymer family, especially HB-PCS, HB-PU, HB-PUSOX or PC with one or more of: a) reverse saturable dye (RSA), b) multi-photon absorption dye (MPA), c) an azo dye, or d) absorption dye, which dye is chemically bonded to the pendant groups of the Polymer (along its chain and/or termini) or which forms a part of the backbone of the Polymer; (2) carbon nanotubes (CNT) as optical power limiters (OPL); and (3) a self-focusing component. This Modified Polymer composition contains the dye incorporated into the polymer chain backbone or chemically bonded to the terminal groups at the ends or along the chain of the polymer, which provides efficient protection from laser beam damage along with its self-focusing mechanism. Cette invention concerne une composition de revêtement polymère destinée à être utilisée comme colorant pour limitation de puissance optique non focale contenant des matières polymères. Cette composition contient : (1) un ou plusieurs polymères modifiés comprenant un polymère, tel qu'une famille de polymères hyperramifiés, notamment HB-PCS, HB-PU, HB-PUSOX ou PC avec un ou plusieurs parmi : a) un colorant saturable inverse (RSA), b) un colorant d'absorption multi-photonique (MPA), c) un colorant azoïque ou d) un colorant d'absorption, lequel colorant est chimiquement lié aux groupes pendants du polymère (le long de sa chaîne et/ou de ses terminaisons), ou fait partie du squelette du polymère ; (2) des nanotubes de carbone (CNT) comme limiteurs de puissance optique (OPL) ; et (3) un composant auto-focalisateur. Cette composition de polymère modifié contient le colorant incorporé dans le squelette de chaîne polymère ou chimiquement lié aux groupes terminaux aux extrémités ou le long de la chaîne du polymère, ce qui fournit une protection efficace vis-à-vis d'une détérioration provoquée par un faisceau laser conjointement avec son mécanisme auto-focalisateur.
