The invention provides an ink jet recording medium comprising a support and an ink receiving layer provided on at least one surface of the support. In one embodiment, a center line average roughness average Ra of a surface of the ink-receiving layer, measured with a 2.5 mm measuring length and 0.8 mm cut-off value, is in a range of 0.3 &#x3bc;m or more but less than 0.8 &#x3bc;m. In another embodiment, a center line average roughness average Ra of the surface of the support measured with a 2.5 mm measuring length and 0.8 mm cut-off value, is preferably in a range of 0.3 &#x3bc;m or more but less than 1.0 &#x3bc;m. An image clarity of the surface of the ink receiving layer is preferably in a range of 2 to 40%.

Ink jet recording medium

An inkjet recording medium, including a support and an ink receiving layer formed on at least one face of the support, wherein the inkjet recording medium satisfies at least one of the following conditions (i) and (ii):

Inkjet recording medium

A base support for an image recording material strikes a balance between high flatness and superb stiffness and is favorably available for various image recording mediums capable of providing high quality. The base support comprising at least base paper satisfying a ratio of subsurface internal bond strength A relative central internal bond strength B that is represented preferably by A/B&#x2266;0.7, and more preferably by 0.3&#x2266;A/B&#x2266;0.7. The subsurface internal bond strength is preferably from 90 to 150 mJ.

Base support for image recording medium and method of manufacturing the same and image recording medium

A silver halide color photographic material comprising a reflective support having provided therein a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, a red-sensitive silver halide emulsion layer and plural light-insensitive layers, wherein the blue-sensitive silver halide emulsion layer contains a monodisperse silver halide emulsion and a yellow coupler represented by formula (I) defined below, and at least one light-insensitive layer which is positioned farther from the reflective support than the blue-sensitive silver halide emulsion layer is a hydrophilic colloid layer containing at least one hydrophobic compound represented by formula (II) defined below, and a relative refractive index of an organic phase containing the hydrophobic compound with the exception of a volatile organic solvent and an amphipathic solute to a hydrophilic polymer thin film which forms the light-insensitive layer is in a range from 0.9875 to 1.0125; wherein said yellow coupler is represented by formula (I) ##STR1## wherein R.sub.1 represents a halogen atom or an alkoxy group; R.sub.2 represents a hydrogen atom, a halogen atom, or an alkoxy group; A represents --NHCOR.sub.3, --NHSO.sub.2 R.sub.3, --SO.sub.2 NHR.sub.3, --COOR.sub.3 or ##STR2## each represents an alkyl group; and Y represents a group which is capable of being released upon a coupling reaction with an oxidation product of a developing agent and is connected to the coupling position through an oxygen atom or a nitrogen atom; and wherein said hydrophobic compound is represented by formula (II) ##STR3## wherein R.sub.5, R.sub.6, R.sub.7, R.sub.8 and R.sub.9 each represents a hydrogen atom, a halogen atom, a nitro group, a hydroxy group, an alkyl group, an alkenyl group, an aryl group, an alkoxy group, an acyloxy group, an aryloxy group, an alkylthio group, an arylthio group, a mono- or di-alkylamino group, an acylamino group or a 5-membered or 6-membered heterocyclic group containing an oxygen atom or a nitrogen atom; or R.sub.8 and R.sub.9 are connected together to form a 5-membered or 6-membered aromatic carbon ring. The silver halide color photographic material has sufficiently high color forming properties, particularly in the blue-sensitive emulsion layer thereof, is suitable for a rapid processing, and is excellent in processing stability.
