摘要： A curable polyorganosiloxane composition comprising: (a) a polyorganosiloxane having two or more curable functional groups per molecule; (b) a crosslinking agent having per molecule two or more crosslinkable groups having reactivity with the curable functional group of the component (a); (c) a curing catalyst capable of catalyzing a crosslinking reaction of the component (a) and the component (b); (d) a pigment which itself does not emit a fluorescent light; and (e) a UV tracer. The composition can be used as an adhesive which is advantageous in that it is easy to confirm whether the adhesive has been uniformly applied to a substrate having a color similar to that of the composition.
