Being the burble sheet to which the burble sheet for stamper reception formation and stamper reception

摘要

The exfoliation seat 3 to which the stamper reception layer 2 which is used for the production of optical recording medium is laminated, we have separating material layer 32 on the side where stamper reception layer 2 is laminated, the separating material layer 32 the Organo polysiloxane which includes the arukeniru basis in the molecule (excludes the next MQ resin.)With, the below-mentioned formula (1) R¹² R² Si O (1)So M unit which is shown (in formula, R¹ shows the organic basis, R² shows the arukeniru basis.)And the below-mentioned formula (2)So it contains with the MQ resin and the building a bridge medicine which include the arukeniru basis which designates the Q unit which is shown as the constitution component, it is the layer which was formed making use of the separating material which does not contain the particle which consists of the inorganics substantially, content of the arukeniru basis in the above-mentioned MQ resin, 0.5 - 5 mass % features that is. According to this exfoliation seat 3, concave fault is difficult to occur on the unevenness pattern copying aspect of stamper reception layer 2.
