Abstract: Provided are methods of applying a tissue marking to a tissue and rendering said tissue marking colorless when desired, comprising implanting into the tissue an amount of the tissue marking in sufficient quantity to form a detectable marking, said tissue marking comprising at least one colored compound comprising a thermally activatable fragmentation group and at least one infrared absorbing compound, wherein the at least one colored compound is capable of being rendered colorless by unimolecular fragmentation of the thermally activatable fragmentation group when the tissue marking is non-imagewise exposed by a source of infrared radiation and applying sufficient infrared radiation to a sufficient amount of the tissue marking to render the tissue marking colorless when desired.

Abstract: A photoluminescent marking that includes a photoluminescent layer and at least one functional overlayer is disclosed. The photoluminescent layer comprises at least one type of photoluminescent material. The at least one functional overlayer is adapted to selectively filter wavelengths of radiation to enhance the daylight observability of a final emission signature of the marking or to prevent the observability with the naked eye of a printed message on the marking. Also methods of making and using the inventive photoluminescent marking are disclosed.

Abstract: In order to provide a golf ball with a water immersion indicator, a golf ball with indicia or a particular recognizable color is overlain with an opacification layer that provides a mask over the indicia or the colored ball until such time as the ball has been immersed in water for a predetermined period of time affecting the ball's performance. The opacification layer when removed or otherwise made transparent, while providing for a change in the appearance of the golf ball upon water immersion, does not need to have a layer or indicia which changes color in reaction to the infusion of water. Rather the opacification layer is either removed or made transparent to expose an underlying colored surface or a surface bearing pre-determined indicia, thus to alter the appearance of the ball when it has been immersed in water for a period of time which affects golf ball properties.
