PROBLEM TO BE SOLVED: To provide an antifogging composition which has excellent long sustainability of antifogging characteristics and antifogging performance, and transparency, and suppresses the adhesion between films when applied to the film, an antifogging layer made of the antifogging composition, and an antifogging film in which the antifogging layer is formed.SOLUTION: An antifogging composition comprises: necklace-like colloidal silica in which primary particles of colloidal silica are annularly bonded; and linear colloidal silica in which primary particles of colloidal silica are linearly bonded. With respect to 100 mass% of the total of solid content mass of the necklace-like colloidal silica and the linear colloidal silica, solid content mass of the necklace-like colloidal silica is 5 to 85 mass% and solid content mass of the linear colloidal silica is 15 to 95 mass%. |
