An object of the present invention is to provide a solid or semi-solid shape which is plastic when it is in an uncured state at a normal temperature, so that the treatment is easy, and the phosphor is uniformly dispersed and coated on the surface of the LED wafer, and can be easily and only necessary. The portion forms a UV-curable adhesive ketone composition of the hardened layer. The solution of the present invention is a UV-curable adhesive ketone composition comprising: (A) comprising R1SiO3/2, R22SiO2/2, R3aR4bSiO(4-ab)/2 units (R4 is a vinyl group) Or allyl), and the R22SiO2/2 unit is a resin structure of 5 to 300 consecutive repeats of the organopolyoxyalkylene, (B) containing R1SiO3/2, R22SiO2/2, R3cHdSiO(4-cd)/2 The unit is composed of a unit, and the R22SiO2/2 unit is a resin structure of an organic hydrogen polyoxyalkylene having 5 to 300 consecutive repeating structures, (C) a photoactive catalyst, and is a plasticity at room temperature in an uncured state. Shaped or semi-solid. |
