There are disclosed an ink-jet recording material having at least two ink-receptive layers mainly containing fine particulate silica on a support, which comprises an ink-receptive layer positioned farthest from the support contains a water-soluble zirconium compound, and the ink-jet recording material satisfies at least one of the following requirements (a) and (b):

Ink-jet recording material and method for preparing the same

A heat-sensitive recording sheet superior in color formation and sticking resistance and excellent in storage stabilities such as plasticizer resistance and wet-rub resistance and printability which comprises a support and, provided thereon, a heat-sensitive recording layer and a protective layer is provided by using as a main component of the protective layer in the case of the protective layer comprising one layer a latex having a softening point of 200.degree.-350.degree. C. obtained by polymerizing mainly a specific hydrophobic vinyl monomer in the presence of a polymeric latex having a glass transition temperature of 50.degree. C. or lower and as a main component of the protective layer in the case of the protective layer comprising two or more layers a latex having a softening point of 150.degree.-260.degree. C. in the inner layer(s) and preferably, using in the outermost protective layer said specific latex having a softening point of 200.degree.-350.degree. C. used in the protective layer comprising one layer. Furthermore, the heat-sensitive recording layer may optionally contain 2,4'-dihydroxydiphenyl sulfone and preferably a hindered phenol.

Heat-sensitive recording sheet

There is disclosed a heat-sensitive recording material comprising a support and a heat-sensitive recording layer formed on said support; said heat-sensitive recording layer containing an aromatic isocyanate compound and an imino compound as color developing agent and a silane-modified acrylic resin constituting at least a part of binder.
