PURPOSE:To obtain the captioned recording medium which gives clear dot picture and is suitable for a secondary original drawing and the like by a method wherein a porous layer composed of bonding resin and a lot of packing particles such as organic particles and the like is provided on the surface of a transparent supporter and dynamical spreading and the like of the ink drop due to collision with a recroding body are restricted. CONSTITUTION:In the surface of a transparent supporter such as glass plate, PE film and the like, a porouos layer consisting of (A) organic particles (e.g.; PS, PE, polyethylene urea, etc., or preferably transparent fine particles, particle diameter thereof is 0.1-3mu) and/or colloidal silica as packing particles of 60wt% or more, preferably, 75% or more and (B) bonding resin (e.g.; acryl resin, PS resin, etc.) is provided. Besides, flocculant for particulate matter for such filler as alkoxytitanate and the like, reforming agent such as silicone oil, surface active agent, etc. are further preferred to be comprised in said layer. EFFECT:Wetting of ink can be restricted. USE:Used for the purpose of an overhead projector. |
