A phosphor-containing cured silicone that is a cured silicone which has a structure represented by general formulae (1) and/or (2) and also has units selected from general formulae (3) and/or (4), the phosphor-containing cured silicone includes a phosphor and particles having units selected from general formulae (3) and/or (4):  An object of the present invention is to provide a cured silicone in which a phosphor is uniformly dispersed, the cured silicone is characterized in that a silicone material has good thermal resistance and lightfastness. In addition, an object of the present invention is to provide a process for production of an LED-mounted substrate by which a plurality of LED elements can be continuously mounted in a batch manner.

Phosphor-containing cured silicone, process for production of same, phosphor-containing silicone composition, precursor of the composition, sheet-shaped moldings, LED package, light-emitting device, and process for production of LED-mounted substrate

The present invention provides a phosphor sheet in which the optical properties thereof are not impaired and which exhibits excellent film thickness uniformity even when comprising large-sized phosphor particles in high concentration. In one embodiment, the invention provides a phosphor sheet in which the content of phosphor is 53 weight % or more of the total sheet, and in another embodiment, a phosphor sheet includes at least a silicone resin, a phosphor and silicone fine particles.

Phosphor sheet, LED and light emitting device using the same and method for manufacturing LED

Provided is a directly imageable waterless planographic printing plate precursor that comprises at least a heat sensitive layer and a silicone rubber layer formed on a substrate in this order and has a high sensitivity not only immediately after the precursor production but also after the passage of time. In the directly imageable waterless planographic printing plate precursor, the heat sensitive layer contains liquid bubbles filled with a liquid with a boiling point in the range of 210 to 270&#xb0; C. Also provided is a production method for making a directly imageable waterless planographic printing plate precursor.
