New organic solvent to microcapsules useful in particular for the embodiment of a paper carbonless sensitive to the pressure and sensitive paper has coated such microcapsules

摘要

The invention relates to a microcapsule is particularly useful for paper carbonless sensitive to pressure, containing an organic solution of a chromogenic agent which is a hydrophobic characterized in that the solvent contains a mixture obtained by transesterification of an oil végétale.de preferably, the solvent will be understood as a percentage by weight: - mixture obtained by transesterification of a vegetable oil 30 to 100% - mineral oil 0 to 70% [invention also relates to the papers sensitive to pressure, coated on one face with a layer of the microcapsules.
