Abstract
The present invention relates to a process for process for preparing a coating by a) applying to a porous and/or absorbent substrate a liquid coating composition containing at least one component having (meth)acryloyl groups and a dynamic viscosity of less than 2000 mPa.s and 0.1 to 10 wt. %, based on the non-volatile content of the coating composition, of an additive selected from polyamides, oligomeric fatty acid amides and polymeric fatty acid amides and b) polymerizing the composition with radiation. The present invention also relates to the resulting coated substrates and to the coating compositions used in the process.
Claims21
A process for preparing a coating which comprises
- a) applying to a porous and/or absorbent substrate a liquid coating composition comprising at least one component having (meth)acryloyl groups and a dynamic viscosity of less than 2000 mPa.s and 0.1 to 10 wt. %, based on the non-volatile content of the coating composition, of an additive comprising a member selected from the group consisting of polyamides, oligomeric fatty acid amides and polymeric fatty acid amides and
- b) polymerizing the composition with radiation.
A liquid coating composition comprising at least one component having (meth)acryloyl groups and a dynamic viscosity of less than 2000 mPa.s and 0.1 to 10 wt. %, based on the non-volatile content of the coating composition, of an additive comprising a member selected from the group consisting of polyamides, oligomeric fatty acid amides and polymeric fatty acid amides.
A coated substrate prepared by a process which comprises
- a) applying to a porous and/or absorbent substrate a liquid coating composition comprising at least one component having (meth)acryloyl groups and a dynamic viscosity of less than 2000 mPa.s and 0.1 to 10 wt. %, based on the non-volatile content of the coating composition, of an additive comprising a member selected from the group consisting of polyamides, oligomeric fatty acid amides and polymeric fatty acid amides and
