Method of making an energetic beam markable

摘要

A method of making an energetic beam markable appliqués ( 502 ) includes dispersing a plurality of bodies ( 110 ) of a first heat coalescable material within a second material ( 114 ) to form a plural phase material ( 108 ), coating a substrate ( 104 ) with the plural phase material ( 108 ) to form a coating of the plural phase material, and patternwise irradiating the coating of the plural phase material.
