To provide a process liquid that improves the scratch resistance of an image and prevents the blurring of the image, while offering high storage stability and discharge stability.SOLUTION: A process liquid contains nonionic acrylic resin particles and a polyvalent metal salt. The nonionic acrylic resin particles have a volume average particle size of 100 nm or more and 300 nm or less. The content of the nonionic acrylic resin particles is more than 2.0 mass%. The average reflectance of light with a wavelength of 400 nm or more and 700 nm or less is 70% or more.SELECTED DRAWING: None 【課題】画像の耐擦過性及びにじみの防止の性能を向上させつつ、保存安定性及び吐出安定性に優れる処理液の提供。【解決手段】ノニオン性のアクリル樹脂粒子と、多価金属塩とを含有し、前記ノニオン性のアクリル樹脂粒子の体積平均粒子径が１００ｎｍ以上３００ｎｍ以下であり、前記ノニオン性のアクリル樹脂粒子の含有量が２．０質量％超であり、波長４００ｎｍ以上７００ｎｍ以下に対する平均反射率が７０％以上である処理液である。【選択図】なし
